Catchy Domain Name Needed for Online Store

I'm setting up an eCommerce shop. Not sure what I'm going to sell yet, but I want a catchy name. Couple of requirements...

1. As short as possible, or at least as few syllables as possible
2. Easy to spell if heard out loud
3. No ambiguous spellings (e.g. is it "blue" or "blu" or "blew" or "bloo"?)
4. Rhyming is fine (e.g. "BlueKangaroo")
5. Should sound vaguely techie or futuristic
6. Can be total nonsense as long as it's easy to spell and say (e.g. "ZapMap")
7. Should be available (and preferably never used previously) in .com, .net, .org, and .biz
