Just make sure the enclosures house the reptiles correctly. I see garbage that is not even worth buying sometimes because it would not hold the reptiles it is designed for in the BEST fashion.....they were probably created by someone that 'read a book' on the animal and has never kept one for an extended period of time.

Make sure your tongs and hooks are strong and reliable. I have spend over $200 on three pieces of field equipment....tongs, a standard hook, and a field hook. IMO...cost does not matter when it comes to field equipment....quality does.

Remember with heated rack systems and incubators that come with a thermostat......the thermostat is what will make or break the product...if you sell a really nice rack with a crappy thermostat...word would get out...and you will not sell near as many....plus you will have people beating your doors down because their animals died or got sick.

Hope that helps!
