get an idea of what N in your area go for.. all locations have regional differences based on economy, and abundance... etc.
now.. take that and deduct 25% for a working hatchet job... and figure up to 2 to 2.5x for a nicely done one.
condition and variables will give the the between ranges.
a n in my area in decent condition goes for about 2k
a hatchet repower might go 1500
a decent funk, MIGHT fetch 4500.. all depends on market.
seen em go cheaper...
