There is quite a lot you can do for under a grand. I don't claim to be an expert on what I'm doing here, but I'm mixing different things that get rave reviews on this board and everywhere else, so I'll lay a pretty good bet it'll yield great results.
Personally, if you're gonna mix it up, I would save the overheads for last. There's a lot of options out there, and the price ranges vary greatly. So, depending on how much you've spent on other things, can effect what you end up with for overheads. That being said, I have a matched pair of Naiant MSH-2s on their way that I plan on using for overheads ($74 after shipping and NC Tax), but you may just be able to shoot for anything up to RODE NT5s, depending on where you spend your money on other pieces of the kit.
My set up will end up being somewhere around these lines:
Shure SM57 on snare top
Karma K-10 on snare bottom
Naiant MSH-2s for overheads
Karma K-10 on hi-hat
Audix D-6 on kick
Only things left to consider are tom tom(s) and floor tom.
For room mic, I'll probably use a Karma K-6, if I use a room mic at all. If not, I may attempt to use it on the floor tom, a leave the tom tom to the overheads.
