Small 5.1 Speakers for my Marantz SR4200 AMP

Hi all, I have a Marantz SR4200 amp and used to run some large 5.1 Eltax
Evolution speakers from it. It sounded great to me, but I have had to sell
the speakers because they literally dont fit in my new house. I am now
after some small (ish) speakers but dont want to spend more than £100
secondhand from fleabay. I dont want the fronts/rears to be any taller than
6 inches, centre speaker+sub size doesnt matter. Any recommendations ?

Do I need to somehow match them to my Marantz ? (I dont know much about this
sort of stuff).

This may sound odd, but I am more concerned about size/price than amazing
quality. I purchased a Sony 5.1 setup from ebay for £35 but my TV speakers
sounded better !!! Dont know what I was thinking....

Thanks in advance
