Here is one we just got that is not too expensive: http://www.spinlife.com/critpath/spe...roductID=74112

Advantages:

Not too expensive
Can be taken apart and placed in a car
Can be shipped to your door


Disadvantages

Not good for outdoor use
Not real rugged
Not much seat adjustment - it either works for you or dosen't
No warranty or other maintenance except at your cost

There may be other options for you at the site.
