If you don't need N-key rollover, the PLU ML-87 is a great choice, but the ebay prices seem a bit high... I ordered mine through a taobao agent, and it was somewhere around $80 shipped. It was one of the more expensive ones on taobao, as I wanted one with browns, in a white shell with blank keycaps. Build quality was better than I expected for the price, and the matrix was fine for gaming, with WASD actually fairly well optimized.
