Uhh, I already have half an arrow shopping list and it might take some time to complete, through trial and error and all that. Tis the woe of too many project ideas, and their slightly limited selection doesn't help. Getting up to $20 would be tough, unless there's something I should stock up on from them.

I see what you mean, if the threshold voltage gets close to the "c-e forward voltage" of the NPN it could resist too much and cause a voltage drop, which I think I've already accidentally simulated.

Also isn't that FET upside-down? With that circuit (with the correct FET orientation) my simulator gives me quite a bad capacitive effect through the resistor from the 212nC gate charge. But as long as my frequency isn't high enough such that either the FET doesn't get turned on fully at all or that it wastes a significant amount of power compared to the load, I should be fine. The voltages shown are at the MOSFET's gate.
