Another thing to look at is the switching speed. IGBTs normally will switch faster.

I use the FGA40N60UFDTU for motor control DC at 180 volts. These are out of you price range but... http://www.fairchildsemi.com/ds/FG%2FFGA40N60UFD.pdf

Also, the higher the voltage the less amps. (stating the obvious) So try to make a coil that will handle say 48 volts and then you might get by with a MOSFET if the switching speed is not to high.

Either way, do not forget a fly-back diode.
