To be frank, that is very less budget for 500 watts per channel + good design + musical rightness if in the market for new/well cared for used gear. It is less even for 200 watts per channel.
If you are not a diehard Maggie fan, you should look at changing the speakers. Cheap muscle amps are not what you should be pairing them with.
You get soem really nice musical amps for arpund 60k. Odyssey khartago is one good example. Pair it with an easy to drive speaker.
