To be honest I had never heard of using a TSTAT for any reptile before I joined this Forum. I don't utilize a TSTAT for any of my lizards, I use overhead heating in the form of flood lights to create a basking spot, and all my lizards like it nice and hot so there is no worry about burning, I know this doesn't cross into geckos, but my point is TSTAT use isn't preached as widely as you would think.
