Thanks for your input guys!
In terms of buying a used rc-62ii, this may be a dumb question, what are the failure rates on speakers? I don't want to drop $250 on it to have it crap out on me the next month or so with no warranty.
Would an rc-62ii be very overpowering compared to an rc-52ii or rc-42ii? Considering an rc-52ii is $280 and the rc-62ii is $350 or $250 used, wouldn't it just be better to get a new rc-62ii for $70 more and future proof myself if I ever do decide to get larger speakers some years down the line? If it were overpowering, aren't there ways to tool around with the receiver to lower the power coming out of the center channel?
