opinions on supplies for Royal Python enclosure..

[LLinz]

So I'm slowly working on upgrading my royal's viv, I looked at pet stores and decided that there's no way in hell I'll be paying those prices! I'm going to get everything online (herpsupplies.com) to save some cash, and I was wondering about what brand and model of heat gun, humidity gauge, thermostat and CHE to get. I'm working on a tight budget, but I still want to get the highest quality and long lasting, accurate equipment possible!
I know a lot of people on here have lots of experience, so I'd really appreciate the opinions! Thanks!
