I haven't ordered from Justdeals myself, but have heard a few people say good things about them... not sure on the shipping though. If you're really concerned about it, you could probably give them a call and ask for an estimate.
Wow, just checked reseller ratings on them and it's really bad. I don't think I'm going to recommend them anymore. I don't know why I was under the impression that they were a good place to buy from.
compuplus has much better ratings and according to pricegrabber it would be about $125 shipped for shipping to my zip code (and they're new).
Are you saying you're going to upgrade the speakers later or not? Future proofing = trying to get something great now so you wont have to upgrade for a while... and then you say you'll be ready to upgrade... I don't understand.
I think those are pretty good for $125 shipped. Logitech makes some pretty decent stuff for the price. I had z-560s for 3 years and sold them for almost the same I paid for them after all that. You'll get better sound if you spend more, but at around $100 I think logitechs would be tough to beat.
