Our lab does carry the IPC-B-24 (copper and HASL, FR-4 and polyimide), the IPC-B-36 (bare copper and HASL, FR-4 and polyimide), the IPC Phoenix board (bare copper, FR-4) and the IPC-B-25A (FR-4, bare copper only). We do NOT carry the IPC-B-25 board as that board was made obsolete by the B-25A. Our test boards are made for us by Diversified Systems (DSI) in Indianapolis and have a pretty good (clean) process. We order by the 100s and so get a volume discount on their standard 4 week turnaround price. This helps out the testers who don't want to take the hit on ordering small volumes, but if you are willing to wait and are ordering a large number of boards, it is cheaper to get the boards direct from DSI.
