They look pretty good but I have no idea how good they are.
I have Logitech Z10' on my PC. In an office size room they are quite simply awesome IMO. Sound quality is fantastic, I can't believe so much sound can come from such small speakers.
I doubt they would be too great in a large room but for a simple 2.0 PC speaker system I dont know better. $RRP here in Australia was $299 but I managed to buy them for $95
