@OP : I don't know what the second hand market is like in your country, but so far the best "bang for the bucks" (if you're a player I mean) gibbies I met were norlinn area ones - they do have a bad rep and can indeed be pretty bad so never (and I really mean never) buy one without trying it first, but there are a few hidden gems that you can get for a very decent price (1000€ or less).
My (other) 2 cents...
The 2nd hand market is decent, but for the known "brands" you rarely come across one for much less than it would cost new. Most people seem interested in getting the full amount they originally payed for it when they sell it. They seem to be clinging to the whole "It's been played, so it's more valuable" concept.
Once in a while you come across one that's listed at a couple hundred bucks lower than the original list price. But they usually contain sentences like "Neck/Headstock broke, but fixed it at this guy in an alley behind the supermarket" in the ad.
I've heard both good and bad things about the Norlin Era guitars, really can't speak for any of it without trying one.
But sadly, they don't come cheap either. You know, the whole "It's been played, so it's more valuable" concept above?
Replace it with the all time classic "It's old, so it's more valuable". Rarely see a Gibson Les Paul from the 90's and back for less than 2000 pounds.
Which is abit sad, as I quite prefer a Guitar that shows some age.
I always try before I buy, so that's not gonna be an issue. If I just knew what to keep my feelers out for when perusing the body, neck, finish and electrics. But I'm getting good stuff from you guys on that department currently =)
