i work at petco so i can see what you're saying, my co-workers arent too bright on reptiles unless im there. at my store we DO carry the zoo-med thermostats, but they're $40 and i dont think they're worth it. i use one and i have to turn the knob just a tiny bit once it turns on cuz thats when it get to 90 degrees. any more and it'll get to over 100 for some odd reason. u can ask the general manager at the store if they can "special" order one for you and u just pay for it once u pick it up.
