Anyone here own a QMaster-Junior?

I saw this on eBay for $100 and it peaked my interest. I'm looking to make an ultra cheap UDS that runs exclusively with an automatic temp controller so this would definitely fit the bill. The few reviews that I have found have been positive and the seller sounds like a stand up guy from what I gather. Just thought I'd poke around here first before taking the plunge.

Thanks for the tip. I'll have to look into the HeaterMeter.
