TBH 900 was chosen simply to allow for dealer markup, bit of figured wood (if that floats your boat) and some luxuries.
If a large scale mfgr can't manage that, then they ain't going to manage it at 1600 either. And indeed price is no guarentee of quality just the same as buying to a lower budget isnt a guarantee of cr@ppiness. It's always a case of buyer beware.
If I was buying a LP style guitar it's unlikely to be a Gibson, in the case of an SG then a faded model would be a potential purchase. Simply down to my perceived value of the instrument
However we almost all have our illogical love affairs, for some it's fancy tops, inlays, custom paint jobs or whatever. For some a AAAAA top is worth 10K I don't understand it but it's their choice
I actually think we are saying the same thing, but we are aimply haggling over price.
But as I said near the start, if you buy something cos it's cheap then it will usually work out a lot more expensive, cos the odds are that you will have wasted your money. Set a sensible budget at the start, don't increase the budget if you see a shiney thing and be wary of absolute bargins. Most of know this but seldom pull it off successfully :(
