I have the "Black Widow" 96" (or close to that) one, with an arc shape, that costs ~$275-300. Works GREAT...you can ride up or walk up under power, or just push real hard, lol. You might also find that one on Ebay from the same company.
The drawback is that it's heavy after you bolt the 3 pieces together. I don't like taking it back apart, so I transport it folded and standing rather upright....just have to use tiedowns.
Don't buy the cheap, flat aluminum trifolds...they start breaking down after 10-15 uses.
