Marco used to have jump ramps in stock. Seems that was in the past, though.
The magnet burn problem damaged A LOT of jump ramps, and that's probably why they're harder to find than most other parts. Plus, without the cliffy protector, jump ramps get torn up real bad (right above the flipper, because the stock ball guide doesn't go high enough). Funny - the part I had a problem with on my No Fear was the standup target assembly. It was surprisingly hard to cut that piece of metal to replace it - it was not meant to be made manually.
