Just an update. Decided to go ahead a buy one since I found a heck of a deal on barproducts.com. Cost about $25 shipped. Went ahead and screwed to the fridge. Have Velcro on the bottom of the tray so it can be removed and cleaned.
The brew in the pic isn't carbed yet, I was taking a taste test. NB Bavarian Hefe, extract kit. A strong banana taste and smell so far. I would guess from higher temps during first few days of fermentation.
Next I'd like to add another tap, and some chalkboard paint above the handles.
