To reverse the system you simply flip the polarity going to the DC motor. Toggle switches (rated for the current your pulling) can work nicely. Or if you need more current I can draw you a schematic for a control using MOSFETs easily available at Radio shack. You can also google H-Bridge and that will be the MOSFET configuration you will need.
I bought 3 DC permanent magnet motors off Ebay and paid about $30 each for them (several years ago). One is a 30Vdc and the other 2 were 50Vdc.
Amtek made some that were VERY popular for people to use for small wind turbine applications (the reason I purchased these 3).
The Amtek DC motors have since sky rocketed in price due to their popularity, but people also use treadmill motors as well.
Wind enthusiasts typically are looking for low RPM (1800 or lower) / high AMPs permanent magnet DC motors because they produce the most power at low RPMs in the wind. But I find them useful for lots of applications since they provide lots of torque.
