I honestly have no good reason for going DBB. It was just one of those "wants" if you know what I mean. I just wanted to spend the money once and have everything exactly as I wanted it, DBB was just one of the ticks.
The money involved for the gain isn't really adding up though, and with a 2nd hand one coming up it might be rather naive to dismiss it due to one, apparently minor, detail. The best price I've been offered on a new DBB is $1600 + shipping. I can get a non DBB for $1000 shipped so i'm thinking I might as well pocket, at least, the $600.
