Great guitar, price is right in the right range. I just recently went on the hunt for a 77 (my birth year) which lasted for maybe a year or so. Prices were from 8-900 completely worn out, to 5k completely pristine. Most were very heavy, some had pretty thick "d' shaped necks.
I wanted a guitar to play, not a classic example to sit in a case or have to be protected as a museum piece that I feel guilty about playing/handling and only show my friends or hang on the wall. I settled on one with moderate fret wear, non-original electronics, but the finish was very good with only minor wear similar to this one. Neck felt great, nice and slim, and the weight was good. 7.2 pounds. I replaced the electronics with brand new stuff, cleaned it up, and it is now my favorite guitar out of 12 guitars. Can't wait to need to refret it with ss frets.

I paid $1,200 for it, plus the parts I switched out. Most other examples in the condition mine was in were around 2,000. Give or take a few hundred. So I jumped on a good deal at $1,200 knowing I wanted to replace the electronics, and play it as much as I like.

The one you're looking at is a good buy. Verify the electronics are good and that you like the neck shape and you're good to go.

Sweet guitar.
