Try Maddog, though even with my bad luck (burning out an MP3+5.1) with Creative, I find the Audigy 2 NX is good. It's one of the few sound, er, cards that you can get at a decent price and plays 24-bit/96khz sound.
Otherwise, you could look at Maddog. They're a, well, cheap company, but have good products for low prices.
Or if you just need basic sound playing, a Sound Blaster 16 PCI will almost certainly work. By far the most reliable card I've ever used, out of the three brands I've tried (Creative, Turtle Beach, and Maddog)
On a side note, does anyone know the conversion for pounds to dollars? Some of those deals look especially delicious if they're anywhere near the same in dollars...
