Small SBC kits for Christmas!

So, every year I like to get myself a little something; this year, I'm probably going to be getting a new computer (outside the realms of this list), but I'd also like to get some kind of single-board kit that I can work on. I'd like something along the lines of a ZX-81 kit, although it looks like those are selling for somewhere around $250, when you can find one. SpareTimeGizmos' Elf 2000 kit also looks fantastic, but I don't have an 1802 or an 1861 to use in the thing, and I'd rather not hunt any down. (If anyone wants to get rid of theirs, though, let me know. *grin*) Has anyone seen any similar kits out there? They don't have to be useful for anything, just fun to play with, and not horribly difficult to put together. I can solder fairly well, and I'm mean with a multimeter, but I don't have the money for my own oscilloscope; I just use other peoples' when they're not looking. Thanks, folks! ~Matt
