I recently did 8 days off road on the Great Divide with a group. Nobody had a Maya. Of 11 folks, there were 3 trailers, one Bob, one Yakima which is a Bob-like knockoff, and I used a Farfarer seatpost mounted trailer. Six people used panniers and two used racing style frame,handlebar and seat bags. They all seemed to do fine, with the exception of one rider who had a pretty cheap set of panniers. I considered a Maya but rejected it since it seemed to be for on-road use only and used a skewer which was incompatible with my bike. If you're going to be on pavement a Maya might be fine. I thought the cart handles on the Maya really didn't add much. For what its worth, I really liked the Farfarer, in part since it only weighs 10lbs and it will break down to fit in a bike box with the bike.
Cost-wise you can probably pick up a used Yakima on ebay for less than $200. Good luck!
