I picked up a second one of the cheap black ones on ebay. I've done the 3V3 mod on one of them, and taken the 3V3 regulator off the other one for 5V parts. I don't see me needing to program 1.8 or 2.5V parts in the foreseeable future.
I don't know, but I suspect that it may be the cheaper option, at least for now.
