Give RSP or Autosaurus a shout. They both do the Gizzmo controllers.
I'm the same, although my greddy works fine. I'd go for the gizmo which can do closed-loop control (greddy just does open loop).I dont know wich is better but i have a profec2 on mine and its been faulty from day one. I too was looking at the gizmos and only hear good things about them to be honest. Im thinking of ditching the profec and getting a gizmo as they seem pretty well priced aswell.
To add to my post, I'd get an Apexi if funds allowedBest one is APEXi AVC-R no doubt...
When i say cheap , I mean CHEEEEAP.They're good but not the best you can have. And certainly not the best value for money that's for sure. If you're an HKS whore get it, will do its job no probs. There other controllers, some of them even cheaper, that are way better though. APEXi AVC-R, Gizmo, etc
