I spend $55 per month on a garage. I would agree that quality workspace is more of an issue than simple storage. Fuselages and wings stack up reasonably well if you're dealing with .40-sized trainers and sport planes. It also helps that I'm married to a wonderfully patient woman who doesn't mind (too much) that I'm using our coffee table in the middle of our living room to build kits.

Needless to say, we don't have guests over very often! [:P]
