Since these aren't in direct competition with Tiny.. Lets post places that we know of that have kits and parts still for good prices.
Need a kit?
Ultimate hobbies has new ones for under $55.*
(Grrr.. $10 more after ebay shipping and I could have gotten a new kit!).
Parts/upgrades?
Horizon Hobbies still carries many of the upgrades (though they are slowly going "out of stock").
List more if you know them!
* Through the end of this month (Jan 04) they have free shipping for totals over $50.
