Not a bad price, very much one I'd be willing to pay in order to get certificates via a CLI.

Ouch, 10x for a wild card? Why do issuers do this? It really puts a crimp on the whole "hobbyist doing hobbyist things" since that's $150/year just to not have cert errors on a single domain.
(FWIW, I'm deliberately excluding StartSSL for a variety of reasons.)
