I own a pair of B&W 602 S3 speakers. These can be purchased used for about 600.00 Oddly enough that's what they also cost new. There's a reason. They're a great value and they are a nice bang for the buck. Most other speakers brands devaluate by a third in a matter of months. They sound great (for 600.00) and don't need much power as long as it's quality. I'm told these were the last of their breed to be built in England. Frankly, to me, they sound a lot better than their current replacement in the B&W line-up. I use them as rear surround speakers now but when they were my mains I enjoyed them every day. The good news is that there are loads of great speakers in your price range. My last suggestion is that you buy something that's used and in great condition. Quality well cared for used gear is as good as it is when it's new except that it's already broken and except for the 602's, usually a lot less money.
Good luck. ps If you go this route, stick with the S3 version.
