During my years of teaching I saw a lot of cheap guitars from Walmart, K-Mart, etc. From those observations I would say about 20% of those guitars are playable right out of the box while the rest needed work, sometimes at a very high cost, to get it in playable condition. Even then they sounded very tinny.
So....it seems it's a roll of the dice unless one has very seasoned knowledge and experience to find a a worthy diamond in the ruff.
I don't think I'd be very good at it.
I bought a tele back in 1979 but I could never afford/justify a Fender back then...probably not now either, for that matter.

So...I bought an Ibanez Tele Silver Series (1977 for 275$) from our lead player when our band was regrouping.
I had pickups replaced in 1993 and it's still a damn fine axe to play...it's the one in my avatar.
Anyway....the video was interesting....thanks.
Carry on....
