thoughts on this infinity amp
 

kay so I have infinity reference 6.5" in the back and reference 4" in the front and the guy at future shop recommended the infinity 7541A to run them nicely. It was on sale for $279. I left figuring I could find it online cheaper but I haven't been able to. Do I buy it from them or is there another amp thats the same qualitywise for cheaper? or what?
