No reply in 15 mins, yea these boards are getting old.
We planned on trying one from POR, but just never got 'round to it. I do not know the exact rate, but I believe they are by the hour. We had a coupon to get 90 mins for the price of 60.
They are small, smaller than I expected. Everyone has a different definition of overweight so hard to say. If I had to guess form just looking at them - I'd say the seat was about as wide as BTMRR. But it looked to have much shorter leg room. I'd search around for some photos to help make your mind up.
