I did a quickie a couple of years ago. I wasn't happy on how it turned out (my fault, screwed a couple of things up, and made a couple of bad choices). I decided to rebuild it, and I feel it now has looks to match the sound quality it produces. I started with a cigar box that I knew would be a little small, but it was the closest size the cigar shop had out at the time. It was too small but I went on anyway, thinking of putting the batteries in a second box. Once I got to the point I needed the second box, I went back. The selection of boxes they had was pretty thin. The manager asked me what I was doing with them, and he got excited and compiled cigars so I could have the box I used for the batteries. He even suggested a lager size to get the entire build in one box. I didn't want to start over and already had the parts for the umbilical.
