Yotantexas, with hopes of maybe helping you out a bit, it looks like you've had 72 views, and no bites. Pricing your items brand new comes to about $35 above what you are asking for used items (taxes aside). Point is, customers get the comfort of warranties and return options when purchasing brand new, not to mention the "warm fuzzies" of HAVING the brand new items themselves. Your pricing may not be enough of a savings to a potential buyer to warrant purchasing used.
I have always liked the Roto's as a good buddy has them on his 3rd gen and he says the extra fuel on hand has saved his arse on more than one occasion. I would be willing to offer $160 shipped to Houston,TX 77089 if you decide on the price drop. I can PayPal the funds to you immediately, if need be. I wouldn't expect shipping to be outrageous seeing as how I'm just a few hours from the Dallas area.
Anyhow, that's my $0.02. Hope it helps, and good luck with the sale. Rotopax truly does make a quality product, and best of all? They're made right here in the U.S. Of A.!!:usa:
