x2 on what gold scud said. I've been looking into buying myself a punt/pram/john over the last little bit, and have been doing my research extensively mostly through people in the interior of BC. From what i've heard, Trackers have durability issues that aren't worth the money you are saving.
Other things to keep in mind, if you're looking for a boat to solely outfit for your fly fishing needs there are a couple things to consider.
1. Whether you want a riveted or welded, both have their advantages and disadvantages.
2. 36" width in the bottom is BARE minimum in a 10' boat if you want to be able to stand up without worrying about tipping.
3. 10' is very small if you decide to think about bringing another person.
I've recently picked up a 9'6 harbercraft flyfisher pram with a 42" bottom!
Hopefully that gives you some things to think about.
