Logitech Z-640s are nice not many places sell them but I think office max has them for $49, they have great sound, long cables and a nice convenient control on the center speaker. The X-530s have control on the right speaker and shorter cables, either one is nice but I like the Z-640s. If you don't want surround Logitechs Z-3 are nice in both looks and sound quality, bit boomy if the subs to high but after a little adjustment they are awesome.
