After many years of not playing anything, I bought an accoustic (Yamaha) - in part because I also had a piano from them. Ditto on they make great instruments for a reasonable price. Deep resonance and tone for about $150. After a few weeks, wondered exactly the same thing -- wanted to learn new stuff, and some songs are more deemed for electric. Now I have both; the electric is a basic Fender model I picked up for about $100, with a small, but powerful amp for about $30 (which, when I use, the volume is set to about 1 or so on both). It's plenty. Also, per the prior posts, and with my fingers just about bleeding I'm having so much fun "picking" up an old passion, the electric is a little easier on those numb guys, and I'm exploring all the nuggets of knowledge into new areas..from folk, to metal, country - whatever is fun. The guitars were purchased at Ron Zehel.
Live in an apartment - an added benefit of the electric is you can get a head amp and not disturb neighbors...so that's my next step if you have that one song rumbling through your head like I do, and expanding your horizons.
