if you dont mind the controller, which i dont mind, i'd look at the cheapest samsung basic or i bought 2 x 256gb adata ones, cheap and fast, can't knock them for the price, not the quickest, but when on offer was the cheapest sdd's that OC and other sites have ever offered so far...
everyone says the samsung controller is better, but have had no problems what so ever with the adata ones so far
