There are some cheap piles of crap out there in guitar land, but you are quite right "low cost does not always mean cheap." Edwards are a great example of this, although they have been sold for years as Made In Japan when in reality they have always been Made In China, they also don't use "real" mahogany they use some cheap Asian alternative. I collect Japanese Les Pauls and i have been able to buy some as cheap as $300 dollars and they eat Gibsons for breakfast. And before the Gibson crowd start crying poor, i have been playing for almost 40 years and do all my own work on my guitars, the Japanese quality is far more consistent than the Gibson's. Bucky, a 150 dollar guitar new is worth about 80-100 bucks second hand, you have to work out what you think your bike is worth and go from there..
