Since you are in the UK maybe contact Pinball Heaven. I talked to Cliffy about the ramp protectors and he was kind enough to tell me he was a couple months back-ordered before I officially ordered. I found some at PH and ordered them. Bit expensive for me due to shipping but for you should be cheaper.

I went with the mantis protector for the scoop (personal preference) but I think their are some scoop protectors floating around. Much easier to source than the ramps from what I found. Shows in stock here - http://bayareaamusements.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=RP-TRON3
