Not bad and yes a little weird but I say $50 in a few months after the .us market takes off a little bit. You have a very flexable domain there, It could be anything from sitting down to sitting bull. Good luck.
$22.50 - $40, IMHO ... at the present time. At this point while you're holding, I would research and consider who would be the *best* folks to possibly contact as potential End user "leads". "Sitting", though strong with search results, may prove a large endeavor.
Best of Luck.
What about a chair or sofa manufacturer? Because afterall they are all about sitting. Don't limit yourself too big companies though there are hundreds of small time but high price boutiqe dealers. Just a thought.
