Dunno where you shop. Got my PCIII for $250. However, I rode the bike for over a year now and found that I don't *need* it. I bought it because one of the other farkles I plan is a full Holeshot exhaust replacement and other slight HP-gaining mods because I'm fat and I get sick of the hooligans slowly pulling away from me on group rides with my pure-stock setup. However, I guess I feel I didn't NEED the PCIII mostly because I've been riding bikes since at least 1/3 of the people who complain about FI bikes were in diapers or swimming in seminal fluid in their daddy's nutsack.
This isn't a Honda Civic. This is a motorcycle. If you're so finicky and, sorry, poorly skilled that you can't safely and effortlessly pilot an FJR1300, please get off now, sell it to someone with the skills and appreciation who can. I lean closer to Warchild and TWN on this topic. Every machine in the history of mass production has some subset of ownership that feels some aspect or another is a problem/shortcoming/tissue-inducing sin against consumer humanity.
Sorry to swing so absolute, but that's just how I feel on these kind of issues. If I wanted a Honda Civic throttle response, I'd buy a Honda Civic or an electric golf cart. It's a gasoline-powered engine, fed by a fuel injected system, which by its nature was difficult to effectively adapt to the type of snapping extremes in use/range that is unique to motorcycling as opposed to more traditional FI uses. Even an Indy Car doesn't snap the exteme ups/downs in a race as often as a typical rider in a daily commute.
Finally, I feel that the FJR tamed down with its hesitation after about 6k mile of riding. Or, perhaps (gasp) my skills adapted subtly in how I rode it to ensure that such happenings didn't return. I nudged the idle speed up a bit (the high end of the manual's range), I give the bike a short bark of throttle when I see that cross-traffic's light has turned yellow. I don't bobble around in very-low RPM range unless I'm slowing up to the security gate at work or at the Navy base, in which case I just put it in neutral and coast, and then (yep, learned response) I give it a short bark of throttle to "clear its throat" (relic of carb days) before I bring it back into gear.
Point made? Either pack some hankies, sell the bike or adapt your riding skills. If you think some other bike is far better, go buy it. this is the FJR. It is what it is and has been. I just don't tolerate ultra-nitpicky complaints very well in this hyper-sensitive world/generation we see now...but I guess I'm just getting old and, in turn, experienced and skilled enough to deal with life.
