Are the ramps cracked or damaged? if not, the ramps on this game can easily be flame polished to look like new. I did mine and everybody thought I bought new ramps. Just be careful with the whirlpool ramp, that's a tricky one to flame polish.
I wrote a procedure for doing this that was later published.
