I built my own 4-piece set about 7 years ago, and played it for a couple years.
I loved the look and sound of some custom DW kits some local band's drummers had but I couldnt afford, so I attempted my own version.
20x18 bass, 12x10 and 14x12 toms on RIMS mounts made from kellar all-maple shells, DW style round lugs, and wrapped in blue sparkle wrap. I paired a DW 5x14 snare with it. That setup looked rock and roll.
But for what I spent back then to build it, I could probably buy a decent level Pacifica set from DW or Gretsch Catalina kit and call it a day. But the sizes I wanted then would have had to been custom ordered so it was kind of a nessesity. I wanted the punchier 20" bass, and my toms mounted off of boom cymbal stands instead of mounted on the bass drum. I could set my drums and cymbals up exactly how I wanted them backstage, and then be carried on by 4 guys, and I was ready to play in under 5 minutes.
