I just two days ago built PC on Intel BOXDP965LTCK
. Although it doesn't fall into your price range (it costs $109), I would recommend it anyway.
Except if you want use many IDE drives - this board has only one IDE connector. Well, most current boards have only one.
Another bit - I built this PC for office use, thereby no overclocking needs were considered. This board likely doesn't offer many advanced BIOS options.
Disclaimer: I honestly have no experience with other suitable boards, thereby I can't say that this is best (or just enough good) board at this price. Currently this is the only C2D board, what I've used
Well, it was choosen based on price and reviews.
