Used Proac Response 3's or Paradigm v 3 60's?

I'm torn. I've heard a pair of Proac 3's (obviously used -- 19 years old, but all four re-foamed) and loved them. Then I heard a pair of Paradigm 60 v 3's and loved them as well. The problem is, they were both in "staged" environments, neither of which is like my listening environment or equipment, and neither of the sellers will let me demo them at home (jerks).

I'm not going to say how much I could get the Proac Response 3's for, but let's just say that, if you could get them cheaper than retail Paradigm 60's, would you? I feel like it's a fantastic deal, but I'm concerned I'd probably have to add more amperage to drive the beasts and they also take up quite a bit of space and who knows how much more "legs" they have. Versus the Paradigms which are efficient, crisp, and brand new. HELP!
