My QT Rack runs a jumpstart, but my main rack runs a VE-200. Like everyone else has said it is all dependent on you and what you can afford or have access to. However if you plan to breed, DO NOT use a jumpstart for your incubator, the on/off style of regulation is a big no-no and will ruin a clutch. The pulse style regulation that comes on the bigger stats is better and maintains a solid temperature.
