$ 1,500 for my baby about 2 years ago
It really just depends, because Jem prices are are sky-rocketing and the BFP's have become pretty highly sought after. (E.R. was charging $ 3,500 - $ 5,000

)
I'd say $ 1,500 - $ 1,750 would be a number to expect for a NICE one

Totally depends on the sellers knowlegde!!
