PET is perfectly fine for manually driven cameras and some motor drives. Its not going to tear the back off the camera. Stop the FUD.
Dale Labs will take it for sure. www.Dalelabs.com They are a great lab.
I don't know if this could be an issue but I remember a processor that had IR film sensors at the edge for repeleshment if PET is used they might have a light pipe issue.
Unlikely though- I think Dwanes are being Über careful.
EDit I think Fleath had the best explaination, the most logical one anyhow.
For this reason the major manufacturers don't normally use PET base for films made for conventional camera use.
The issue is more of stripped gears in wind mechanisms because the film doesn't break or the perforations tear. Some cameras are far more robust than others but many of the low to medium priced cameras made in the last few years don't have the build quality of similar cameras made in 70's & 80's.
Ilford's comments were because there has been damage to cameras, so it wasn't scare mongering, it lead to their rapid withdrawal of their 72ex 35mm film, so they know what they were talking about.
I also have had my digibase returned by Dwaynes and it is sitting on my dresser waiting to find a place to send it. I was going to send it to york's but they send their c41 to dwaynes.
Samy's store in Santa Barbara does dip and dunk E-6. $5 a roll plus return postage.
One only has to think of a over-vigorous manual winding-on when No 36 or No 72 has been reached (I've torn conventional film that way before I knew better), and you have a problem when the film stays put! Clearly Dwaynes have similar concerns...maybe overcautious, but they know their equipment, and I wouldn't be very pleased if my film were damaged because of someone else's PET film being spliced in the same reel.
Poleyester film has the distinct possibility to damage auto-winding systems, depending on the force exerted by the winder, and where the force is exerted on the film. As for manual winding cameras, as long as you don't force it, it will be okay. The problem is that most people's reaction to a stuck wind lever will be to push it more, which will damage the mechanisms before the film.
