people flogging new ramps have to say something negative about NOS stock or they wouldnt make a dime flogging new ones.

I have no financial intrest either way, but would always go for a better product if I could afford it, for not much more (sometimes less) than NOS I can have a brand new, much thicker, better product.

Just look at your current machines which all carry the orig ramps. Except for wear that is due to massive commercial on site usage, all ramps are still as tough as nails and look great.

Not true, check out most games and by now they will have cracked ramps, even those with minimal use, there are games such as WH20 where the 2 ramps beside the 'no way out' entrance are so thin at the exposed ends that on all games they are totally trashed, I have not seen one, or heard of one that isn't.  I needed to replace both. There is no way I would waste my time putting originals back in there, they are a pain in the ass to change anyway for them to break again in a few years, few weeks, few days??? who knows?
The new ramps are so much thicker that I am confident they will never break, I do not have ramp protectors on the and am totally satisfied with my purchase.

Have you actually seen one of these new ramps?

Before you state that people are trying to 'flog' them maybe you should have a look at one and see for yourself.
I have never seen Greg on any forum trying to "flog" his ramps or stating anything negative about anything. They sell themselves.
