FTF...your words:
"....it feels pretty good to play. It has a nice sound, and just a tremendous vibe to it. I like it, am drawn to it..."
That's the bottom line to buying a guitar.
I agree with everything said here, but...Recently, I went into my local guitar shop to look at the Epiphone John Lennon special re-issue. It's a Epi Casino made to the original Kalamazoo, Michigan specs. The guy there told me that even though Epiphone is owned by Gibson, all Epiphones are now made in Korea which probably means that Samick is the manufacturer. Samick is known for low price but not for great quality. However, they manufacture for alot of different guitar companies.
Based on that comment, I am now thinking about a Gibson ES-335...obviously alot more money but I intend to own it the rest of my life.
If your Epi is older, it may have been made in Michigan and be a great guitar. If you're happy with it, buy it.
Remember, a man can't have too many guitars.
Good luck.
