I'm pretty interested in giving this a go. Here are my questions:
1. Is there an honest way to get an empty keg, or do you just go put down a deposit and then never go back and get it?
2. Who does this, what are the ups and downs? It seems that a keg is a bit taller than a kettle bought to boil with.
3. What types of alterations does it take? How hard are they to do?
4. What's it going to cost in the end to have a functioning kettle from a keg. Pretend it was 50 bucks for a deposit.
