Logitech customer service is indeed excellent. when my friend's logi speakers went down, i just filled out an online RMA form for him, and the speakers came in the mail not too long after. they didn't require us to ship the broken set =)
i would look out for the g500. it occasionally goes on sale on newegg for 34.99 w/ free shipping.
i would have got one, but my g5 is still going strong after 5 years - except the sensitivity buttons ...
