so i built my first rack over the weekend. I was bored and i had some extra money and my collection keeps growing. I used 1/2" mdf board, pegboard, wood screws, satin black rustoleum paint, and wood glue. (ps i would highly recommend using 3/4" mdf board rather than the 1/2" when building a rack.) I will try and post pictures later today. The question now is what thermostat to go with. I'm sure in the future i will need to build another rack and i was wondering if it just made sense to go with the more expensive helix thermostat ($130) or a cheaper model (zoo med or big apple deluxe). I like how the helix regulates the temperature and i just feel it would be better in the long wrong. Any opinions would be appreciated.
