I was talking to the dealer and they said they had a factory boot go within a month -- probably wasn't installed correctly. Anyway, in CAnada they wanted $90 for the boot. I would prefer the factory boot, but in this case I went with a REIN one for $20. If it breaks, I'll change it again with a factory one. The other side (driver) is so far 25k mi and going strong. (it was a non-factory one). HAving said that, if I had access to the factory boot for the US price at the time ($40), I would have totally gone for that. I was in a bind and needed the job done quickly, so I didn't have time to order the part from the US.

Thanks!
