Cylinder Head Flow Bench?

Anyone know any cheapish options for a flow bench? I would love to see some numbers for my porting I do. I would like to find something under $1500 is there used equipment out there for that?

Also I don't mind building something but it would have to be accurate enough to use the numbers

Thanks

I have a Superflow bench that is set up for flowing BB Mopar heads. I'll sell the bench with all of the custom CNC machined parts for $1500. I'm near Portland OR so that shouldn't be too bad of a drive for you. I don't think I'm up for shipping the bench since it would require some custom packaging and probably disassembly. PM me on the board if you're interested.
