I worked with ET a few months ago, when I bought my S10 used. He emailed me the forms I needed, he stepped me through the process and even told me that I may need to get my bike inspected at a local Yamaha shop. I did as he instructed/advised me. Took it to the shop, they didn't inspect the bike even though they could have, and I had the extended warranty. I too am a happy camper.
I do understand that you can get them a little cheaper in a few other places, but personally, I'm willing to help out some that directly or indirectly helps the forum. Especially when you get excellent personal service. If I ever get down to ET's part of the states, I'm going to drop by his shop and say Hi.
I will probably be using the warranty in the near future as the knob on my rear shock isn't working. And I understand that they will replace the whole shock, and not just the knob (another thread).
