My vote is for Herpstats. I have 4 of them and they all work great. They have more bells and whistles than the VE ones but also cost a little more but the software on them is upgradable. Dion at Spyder Robotics said you just got to send them in and pay to have them upgrade it and send it back. So that's nice in that your Herpstat wont become outdated when they add new features like the basking light feature.
