Since no one else has chimed in, I'll tell you what I know about them.
I have one of their units on my 55 Handyman. It is an older unit and last year the motor started getting hot and stopping. Not good when it's pouring rain. I had to stop and apply RainX to the windshield on my way home from a show on the other end of Tennessee.
Anyway. I checked into getting another unit and found similar prices.
So I emailed them so see if I could just get a motor and they said they can replace the motor for under 100 bucks. I sent it to them, they fixed it and sent it back. Works great.
So, I guess what I'm saying is they have good products and good customer service as well.
