Much appreciated! I've been scouring eBay, Reverb, Music-Go-Round, Guitar Center used gear, Sam Ash used gear, and Craigslist (ALL Craigslists across the US), without much luck on these. I may end up just getting Saturn 3 bass drums, but that 15" Orion tom is probably gonna be a pain to find. I'm holding off on going the Saturn route for now, just in case I can find an Orion kit with the 15" and one (or both?) of the bass drums I need. However, if I find the 15" Orion separately, I'll likely just buy Saturn kicks since they're pretty easy to find.
It all started on Craigslist actually... Stumbled across an endorser-owned Orion (not Orbiter), with a well-toured red sparkle custom paint job. The chrome hardware is all excellent though - 10x8, 12x8, 13x10, 14x14, 16x16, 18x16, 24x16, 24x16, 14x5.5 snare, and three heavy duty Mapex tom stands with four tom arms... $750. Then I recently found a green 8x8 on Reverb for $100. I plan to refinish the whole lot once I get these last few drums, so color doesn't matter.
I had originally intended to split the kit into two, and sell them separately. Probably could've made a couple/few hundred bucks. Then I started thinking about just rounding out the bunch so no matter what the gig, I will have the ability to put together the perfect kit... Which brings us here.
