hi i already own a 5.1 system for my living room. paradigm to be exact. but i want something small and cheap for my bedroom. i went to a pawn shop the other day. put 50 dollars down on the panasonic sa-ht75. they are selling it for 165 dollars in canada. its a 5 disc changer which is a bonus built in amp ect. sub sounds good. or should i just get my 50 dollars and forget it.
