How can anyone call any Martin "cheap"? In the UK they start at well over GBP 500, more likely about GBP 750 (and that's the awful thing made of chipboard). Welcome to the real world.

The used Guilds, about two thirds of that. Still not cheap. And a bit too trebly for many.

Cheapest Seagulls - about GBP 300. Not "entry level" by any stretch (and seem very susceptible to the B string going out of tune for some reason).

Ayers or Dean Tradition (I much prefer the sound of the Ayers) about GBP 200, or second hand about GBP 100. SOrt of "good beginner" standard.

But there are real "entry level" guitars from GBP 59.99 out there (starting to claim solid tops at about GBP 79.99) and they are every bit as bad (well nearly) as the worst cheap rubbish from the 60s.
