Vinotemp lists replacement parts for the 28 bottle units. I considered purchasing the parts to make one. The prices for the replacement coolers and controls weren't that bad.
But you would still have to purchase the power source and controllers, which will bring the price up.
I'm still in the 'research' stage. I'm trying to do it as cheap as possible.
I found this a while back and tried to email the guy to see if he had any updates or suggestions, but I never heard back from him. He did a fantastic job from what I can see.
You won't be able to find anything you can just place in your humidor. You will need to have something go through the back, plus all the controls, etc.
You can purchase thermoelectric cooling units for places like this, I'm sure they have the controllers as well.
You can check here to see if a local Target has one available.
It's the 28 bottle Vinotemp.
Why are they so good? Add a few Spanish cedar shelves and drawers and you have a 1000 count climate controlled humidor. You can't find a 1000 count climate controlled cabinet humidor for anywhere near...
You can use this link to try and locate Spanish cedar near you. WoodFinder, put Spanish cedar in the "Search by key word' box and enter your zip code. It will show you retailers around you that carry it.
If that doesn't work, I take P.P. so you don't need trader feedback.:tu
