looks like you paid 3950 for the one in stock

okay looks like you have 1 in stock

and you want 5000

you should use an escrow to sell it

and 5000 is actually a fair price to a USA buyer. the reason is  if you buy from this person  and are in the USA the gear is in the USA (PA)
you the new buyer did not import it so you would have zero worries if you buy from this person about the trump tax on imports.
