Not at all.
A quick Gatherer Search revealed at least 25 non-Green, fairly inexpensive basic land searchers (most $0.10 commons). Key cards of note:
The Panoramas: Example Bant Panorama, Naya Panorama
Terminal Moraine, Evolving Wilds, Terramorphic Expanse, Ghost Quarter, Oath of Lieges
Artifact Searchers - Armillary Sphere et. Al.
Probably, the best way to store a cube is in a properly sized corrugated trading card box. These boxes are fairly cheap, and with your local friendly game store's 100% markup, they shouldn't run you more than a couple dollars.
I wouldn't use booster pack boxes or shoe boxes. Booster boxes are too flimsy, because the are designed for display purposes. You ...
A good mana base is required to have a good deck. The question is, how do you want people to achieve this? Either they play spells that're easy to cast or they have good fixing. Duals are fixing without an extra slot or tempo loss. Worse fixers either cost cards or tempo. Like the lands earlier suggested (Evolving Wilds, Taplands, Shimmering Grotto (ugh)) or ...
The first thing you need to do is decide which colors you want to support the reanimator theme in. Black is the go to answer, but there are solid reanimation options in white as well. Enablers are going to be mostly blue or green. Once you know the color options, then envision what you want a good reanimator deck to look like in your cube. Do you want it to ...
The cardboard boxes that come with "fat packs" are sturdy, reasonably portable, and visually appealing. I don't think one can hold 750 sleeved cards, but two should be sufficient. Third-party online shops often resell just the boxes individually for a few dollars.
Players are going to need to sleeve up their basic lands anyway, so I see no reason not to put ...
I think it depends on what type of cards you've included in your cube.
I remember that the Invasion block had lots of mana fixing because they wanted to encourage multi-colour deckbuilding due to the Domain mechanic.
On the other hand, Mirrodin block didn't require much (except for colourless splashable Myr) due to the artifact-heavy nature of the block.
Mono-Red. Aggressive creatures and burn.
White Weenie. Aggressive creatures, cheap removal and equipment.
Mono-Black Aggro. Aggressive creatures, removal and discard.
U/W Control. Counterspells, board wipes, removal, card draw and a few big finishers.
5-Color Control. Like U/W but with more powerful spells and mana-fixing.
Reanimator. Put fatties in the ...
At the MTG Salvation forum (http://forums.mtgsalvation.com/forumdisplay.php?f=349) there are several categories regarding cubes. You can post your cube list (1000+ there already) there, but also discuss cards and archetypes.
The best place that I know of is http://www.reddit.com/r/mtgcube
Other options include tweeting the link to your cube with the hash tag #mtgcube.
Quite often if you do one or both of those, people will draft your cube using cubetutor, which will then give you drafting statistics about what cards are taken highest, and you'll usually get direct feedback ...
Important cards to consider (if you like the most powerful ones)
Dance of the Dead
Thirst for Knowledge
Akroma (white > red)
Angel of Despair
I would advise against getting dual lands or shock lands. First of all, they are only good in decks where players are running those colors. If we assume everybody runs a 2-color deck of randomly chosen colors, there's a 10% chance that this card would be at all useful to them. Terramorphic Expanse/Evolving Wilds, Shimmering Grotto, and Manalith on the other ...
Everything is possible, YOU decide what is fun and how you want to build your Cube. Here is a detailed article on the basic of cube building.
Basically, it depends on :
Budget. Fetch lands and original dual lands are expensive
Power Level. They allow to build more reliable decks than any other duals (that's a reason why Legacy and Vintage are more powerful ...
I highly suggest a cardboard box. I got a 1600 size box for about $10.
On the topic of lands and tokens, I keep 60 of each basic land (so 300 in total) with the cube at all times sleeved. my cube is from Khans/fate/dragons so tokens aren't really an issue, however I keep 10 of each token sleeved in a different color.
I don't recommend using the cub3 from ...
