I just finished the board and placed the order though OSHPark. Only $45 shipped for three boards!

I've also finalized my speaker driver decision as well. Due to my limited access to tools, I wanted to be able to simply cut holes in wood with a scroll saw and mount the drivers on the outside to cover up any nonuniformities. I found some great drivers on Parts Express that will do the trick:

Tymphany BC25SC55-04 1" Square Frame Tweeter

Dayton Audio DS115-8 4" Designer Series Woofer Speaker

I'll be ordering these shortly as well as a bass port. Considering I just started actually working on a schematic perhaps a week ago, this is coming along pretty quickly! Here's hoping my boards find a spot on an almost-full panel and I get a free upgrade to their super-quickturn service again...
