in my opnion buy a used boat of higher quality.
I got a 15 year old Maravia for less than a grand. It holds air beautifully, has only a couple patches on the tubes (the floor is lace-in and has taken some beatings).
In ten years, I'd guess my used old boat will be in better shape than a new-today Star or other Chinese made boat. The PVC/Urethane that Maravia uses is super-bomber.
edit to add:
just posted today, it' hypalon, it's 11 years old, and for the price of a star you get dry boxes, oars, frame, etc.
oh. right. you want something bigger. well...you get the idea
