Aaron hit it on the head- the amp must be able to handle low impedence and have high current to drive the Maggies. At least 125 WPC doesn't hurt, either, and 200 WPC would be better.
Don't get wrapped up in the 4 ohm power rating. Speaker power requirements (and an amp's specs) are generally stated assuming 8 ohms.
My recommendation? Counterpoint SA-20 or SA-220. Around $700 used and a truly great bargain. After trying six carefully selected amps (including an SA-12 @ 100 wpc), the SA-20 was the easy winner with the Maggie MG12's.
