Actually, Rick $295 is your cheapest listing on a Hobie 16 trampoline on that link.

Reading the costs on the Sunrise link the Hobie Factory H16 Tramp is actually $5.20 less than the cheapest one shown there and $71 bucks less than their one designed to last.

On the Hobie 14, for mesh materials it is a $21 difference on comparison below.

From Catsailor listings:

syp-h-14bks Black Mesh, Standard Thread $295.00
syp-h-14bkt Black Mesh, Teflon Thread $337.00
syp-h-14bus Blue Mesh, Standard Thread $315.00
syp-h-14but Blue Mesh, Teflon Thread $357.00

So...

A Hobie Factory Built Mesh tramp for a Hobie 14 is $378.00 (you can choose black, grey or turquoise vinyl mesh)

Compared to an after market tramp with black or stock blue color AND the required Teflon thread to help it last 5 years? $357.00

$21 bucks less then? Not so radical really.

And...

You can get a factory built white vinyl tramp for $294.00 Thats a buck less than the after market one with the base material and base thread.

The factory tramp is actually $1 less!

Its Class Legal, you get a nice choice of mesh colors if you want... and they don't chew up your knees like the after market materials do. Plus! They will likely last much, much longer than the stitched ones... no structural stitching.
