Hi Eric,
I too took the plunge into the Harp Guitar world in December.
I bought a Holloway HG Model 5 Natural.

Recently got my electronics set-up all squared away. Sounding good.
I will agree about the learning curve. Pretty steep, but slow progress
has really been rewarding.
Stephen Bennett just released two Harp Guitar instructional DVD's.
Available at his web-site, the Harp Guitar Music page of Harpguitars.net.
and Truefire. He plays in a different sub tuning (Bennett tuning=high to low
G, D, C, B, A, G. which requires a different set of strings)
Lots of fun and potential, just need to find the time....
Mike
