Hi, Gwen -
I agree that there are many better harps available than the Harpsicles. However for the size/weight and especially price, the 'Sicles are respectable.
The advice to "try before you buy" is always good, and especially so before investing significant $$ in an instrument. The world of folk harps is a chaotic and undisciplined place compared to, say, the world of mandolins or even guitars. (I'm referring to the range of instruments & construction styles, not necessarily the players). There is little standardization of size, performance, or construction technique.
As for playing wire ("rarer and more difficult", as the T-shirt says), I may take that up at some point. There are a few of that ilk around here (San Francisco region). Ann Heymann recently told me she thought I was a wire player at heart (how's that for name-dropping! *g*). I may take up the traditional clarseach in the future, but my current focus is to finish building the harp I designed (31-string, mostly nylon with bass wires) and expanding my playing style to accomodate this greater range - I've been playing 22-string quite happily for a few years.
Keep on pluckin'...
