You might want to look into Ghurd's controller. Its really simple. Only thing you need to know how to do is how to solder it togather. Which is really not that hard at all. You might even be able to work out a deal with him to solder it for you. But I wouldn't know if you could work some deal out.

Thats probably the cheapest solution.

Here's what I'm using now on Ed's minigen200 that's up a pole in my backyard...

My current charge controller is a double pole double throw bayonet switch and a voltmeter.....paid $3 for the switch (radio shack) and $3 for the voltmeter at harbor freight......
Hook your turbine to the center taps on the switch, your battery to one end, and your dump load to the other....

Hook the voltmeter to your battery....and when your battery is fully charged (14.4 volts), flip the switch to disconnect the battery and connect the dump load.
And when your battery starts getting low, flip the switch the other way.....

I've got a 115ah deep cycle battery connected to one end of the switch and a great big 12 volt space heater connected to the other end...

My little wind turbine doesn't charge that battery very fast, so if I'm late checking the meter, I don't think it's going to do very much damage....and it might even act as "an equalization mode"
