Oh, now I know what it is, I think--it is an E Z Ryder. I didn't recognize it at first because the photos I have are of one with the steel wheels--I didn't recognize it with the wire spoke wheels on it. I thought they were less than $2000 to buy though? I haven't seen one in person. We did compare to the Smart carts, thinking maybe we'd go with the EZ Ryder because it was cheaper, but then decided that after having one Smart Cart we might be disappointed in anything else and so got the 2nd Smart Cart even if it was a bit more money.
I did have a website from one of the dealers (he also sold Smart Carts) but someone commented recently that the EZ Ryders are no longer being made. I don't know if that is true or not. I'll have to hunt up that website.
