I already have the external thermostat. Funny, 'cause I was looking at Lowe's the other day and saw a chest style freezer that I thought was the perfect size to hold up to 4 corny kegs and a tank for under $200, but I was stuck in the "FREEZER" mind set. Looks like I will be making a purchase tonight!!!
On the topic of towers, has anybody made their own tower? I have taps, tubing and fittings. I did a little online shopping and was not impressed with how expensive two or three tap towers are!!!!
