I've used Aerius and Aerius i's with both a B&K AVR202 receiver (105 w/ch, home theater) and a Bryston 4BST amp (300 w/ch, stereo setup) and have been pleased with both. Whatever you do, I suggest going with at least 100 w/ch; 200+ is ideal. The ML electrostats like current; so blend well with amps that can handle low impedences.
You should be able to find units with 200+ w/ch from Bryston, Aragon, and McCormack for around $1200.
