Bentley's is just up the road from me, and I was in on Wednesday asking about having my captain's seat re-padded. If needed, I can go plop my behind in a Rivermaster if anyone needs an opinion.
My opinion right now is that they are damned expensive...
BTW, Bentely's does great work. The did my curtains, mooring cover, camperback and reworked the King boat cover. I think that the pricing for these items was reasonable...
