I myself have a Martin Alternative-X. Newer guitar made of composites with a brushed aluminum top. People always gawk at it when I open the case, it sounds great unplugged and also has good electronics (Fishman Prefix Pro) so its AWESOME hooked up.
There she is...or one like it. I plug it into a Berhinger Ultracoustic ACX 1000 amp, 2 8" speakers driven by 2 60 watt amps. Shure Microphone/cable/stand.
I bought it at Guitar Center, and the final battle came down to it and a Takamine. I liked the Takamine, it sounded good and they were both thin body acousitc/electrics. They both played well, but there's just something about a Martin and their reputation that made me opt to spend a few hundred more bucks. I don't regret the decision. I'm looking at Taylors now since I'm getting serious with the playing, and maaaaaay be convinced to part with it at a pretty good discount to you. Try one out at your local guitar store, and let me know what you think.
I use Martin SP Lights or Elixir Polyweb Light strings
$700 would be right about bargain basement price for what i'd let it go for, including case.
I'm sure you've heard of Dispatch, being from Boston??? I'd say the're my favorite band and a new up and comer, Pat McGee band from Virginia is a good one to check out as well. Dispatch just played their final show, I was busy that weekend so I missed the show...
Never did get to see em live, but have plenty of live stuff on mp3 and CD
