Wow, your dad has great (and expensive!) tastes in guitars.. i have an Epiphone SJ200 Jumbo, which is basically a cheap knockoff of the one you mentioned your father recently bought.. Epiphone and Gibson are the same company, but the one i have retails for about 1/10th the cost of the Gibson model; i think i paid about $350 or $400.. still, it sounds good to my amateur ears.. before that, my first guitar was a $200 Yamaha and it sounded really good for that price point.
