I'm in pretty much the same boat as you, first year breeding and thinking I gonna need to get an incubator before too long. I've been looking at the ones here: http://www.jwexotics.com/economyincs.html they're pretty good price and you can get ithem with or without the thermostat.
Oops! I meant to say JW, not J&J. Always getting those two confused, especially since each one has sold me a snake. I may just go with JW's, since I have heard good things about them - whereas the Hova-bator seems to have mixed reviews.
