The only amps in that price range I can think of that can drive that very tough load are a used Innersound ESL, if you can find one or a Wyred4Sound amp.
20.1's are some of the finest speakers ever made, period. But one of the problems with that, is that they reveal the limitations of the equipment upstream of the speakers like few other speaker in the world. You will usually see someone spend, estimated, quite a bit more on the amplificatoin with Magnepans (especially the 20.1's) than they do on the speakers, usually by a multiple.
I have never heard the big Maggies with anything less than about 800 clean, clear expensive watts in a 4 ohm load. They usuallly match really well with the big Bryston Amps (7b sst2, or better the 28's), or big Pass amps (sweet). You need a lot of current to move the bass panels on those speakers.
Good luck, great speakers.
