Will - Just my opinion here. You cannot make a mistake buying any of the saws from the small makers mentioned on this thread - every single one of them make incredible quality saws that are light years away from what us poor hand-tool schmucks could get as little as 15 years ago, where the market was populated by extremely bad British versions with incomprehensibly thick saw plates, unacceptably shaped totes, and inappropriate cross-cut teeth.
What I would note is that you should simply buy whichever one of these saws appeals to your aesthetics and pocketbook, because whichever one you buy, you will adapt to the saw's specifics. At this level, it's dang near impossible to fit the various saw's peculularities to your existing preferences, both because of the logistics of trying out all of the brands on the same day/same wood, but also because the differences are subtle.
One final thought - I own a lot of back saws (probably way too many), from Lie-Nielsens through Wenzloffs to many 19th century British antiques when they were still making superb saws. Every one of them performs slightly differently, but not so differently that each one is not a pleasure to use. My one caveat here is that you may wish to eventually own 2 rip-filed tenon saws - one with at least a 4" depth of cut to allow for bigger projects such as workbenches, outdoor furniture, doors, etc..., and one that's in the 12" range for small projects like spice boxes, miniature furniture, small cupboard doors, etc...
