I bought Axel to take my mind of stress of life, and to be a hobby
i could not have said it better myself, i too am in the same boat, i had a BP when i was a kid, and i bought another one now for the very same reasons as you.

Not to hijack your thread, but kind of the same question, right now im using a 15 gallon tall tank with the smallest UTH on a new pastel i just purchased, this tank will go to my younger normal BP, which is on a 10 gallon. Anyways, next expo is in july, which i plan to go and purchase a new tank and of course a bigger UTH, more aspen bedding and other supplies, and at the same time i want to purchase a thermo to go with the bigger UTH, as opposed to the dimmer i have hooked up now.

My budget is between 70-80, maybe a 100, whats the best for that price range? (under 100)

i looked at thermo's on ebay but im completley lost on what i should be looking for, i keep getting alot of stuff that looks like it should be hooked up to a boiler for a school cafeteria or something.. any links to the ones you guys are using?
