I dunno how much they go for on average, but I do know where I can get them in tested, like brand new condition for $25 (yes, it is a sale, though.. but it has been on for a while). On eBay you're probably looking at a little more, esp. tested.
The same place has B boards cheap and in abundance, but no SFA3. If they did, it would go for $50 or $75 (I would assume -- Marvel vs. Capcom is $75 there).
Clips and mounting tabs vary, usually @ $5 or $10.. I'd have to get these off eBay anyways.
I would go as high as probably $85 + s&h for what I need.. I wouldn't go that high, but yours is tested and SFA3 seems to be a hard find.
Don't kill your auction, though. To be honest, I can't afford to expend another $85 until next payday. I also haven't finished a rig for my CPS2 setup so I fear the boards dying in storage

So unless you can wait or let me PayPal you.. <sigh>
