Hi Dave,
Looks like a Meade mirror off ebay outlet? I got one of those and am planning to build a dob around it. Here is what I did so far. I downloaded a copy of Newt software and designed my OTA in that using the primary and secondary mirror I got. The made the parts list and so far the ones below.
OTA
12"x48" sono tube from local hardware store: 8$
Spider and Secondary holder from Destiny ebay store: 26$ Shipped
2" Rack and Pinion Focuser: 30$ shipped from Astromart
Primary Mirror Cell: I am going to make it myself. Plop software helps a lot in making simple design
Finder: Have finders lying around
Dob Mount: Homemade
Teflon, edge rings, altitude bearings
I am thinking the total cost of the project including the mirror and secondary to be somewhere around 400$
good luck and keep us posted.
