ebay and amazon are good resources. If you have read my posts, you will know I strongly recommend the STC-1000 digital thermostats. I use 12V fans running on a 9v motorola razr phone charger.LOL! Oz, you and Sally have inspired me! I'm getting a Coleman 24-can Party Stacker cooler next week that I'm going to convert into a coolerbator. I saw your post on the Diary & Notes ~ Air Cell Detached SHIPPED Eggs thread, for the Bordeaux Bator, and liked some of the features you used in yours. So, now I'm on a mission to find the parts, and make my own. I just don't have the space for your "display" 'bator!
good luck
btw - my non shipped eggs in the display case were due today. we have 10 hatched and 2 zipping. I think Bernie has 25 due today and 21 more next week.I get confused keeping track. I should have this weeks photos emailed to me today. i will post them in my thread overnight.
