Like with so many airsoft toys, it's apparently been "only fielded once". Buying/building one to keep, I can get. Heck, put it in your will that you want to be buried with it (me, that's my Paul Binns sword). Buying/building one to use once, and then get regrets over, eh, not so much.
Not listing the secret extra amount of PayPal fees that you'll want added on is disgusting. I mean, I feel viscerally repulsed that anyone could be so fracking lazy as to not bother to work out the number that they're going to have to work out anyway once they have an interested buyer. Not to be hyperbolic, but it's literally worse than Hitler.
