I currently own a 1949 Southern Jumbo, which I am planning to shift at some point, as I find anything larger than an OM or 0000 just too big.
My other guitar is made by Ron Pinkham of Woodsound Studios Maine, and it's a great-sounding piece, here's a link: Pinkham clip
My favourite all-time shape is the L-1. I played a 1930's L-1 today that had a delightful sound.
