i am looking into getting a thermostat maybe. i don't have a lot of money at this time, so im debating in getting a zoomed repti-temp 500r, or using a basic dimmer switch. If i have a digital thermometer with a probe then i could use a dimmer wired up for 2 uth's for now right? i'm trying to save up money to build a custom enclosure for my bp, thats why im not looking to spend over 50 bucks right now. I know that sounds bad, but she needs a bigger tank asap. thanks
