Looking at an old listing here for a Torker DX, I’m positive you’re right 
And yeah, so far I’m leaning towards not getting it. If it was closer I’d absolutely snatch it up, but for a 5 hour trip it’s a bit of a deal breaker for me.
In terms of second-hand market around here, interesting unis are few and far between. Though I assume that’s the case for most places (and for “interesting unis”, that probably depends on who you ask! ). It’s mostly entry-level 16"/20" and vintage cottered unicycles
EDIT: I guess while I’m on that train of thought, where would y’all look for second-hand unis in person? I’ve been through a few thrift shops a while back, though it seems only a few locations sell used bikes. A local bike co-op does have a few old unis; it’s been 6 months or so since I’ve been there so I’d like to check there again when I have the chance
