What would you take (trade question)?

I want a Glock 35...I would like to trade my Glock stuff I have now for it. So here's the question: what would you be willing to give ($) along with the following items to get a NIB G35?

Glock 23, 95-100%, original Glock box and factory accessories
4 drop free mags
G23 Fobus holster
G23 tactical leg holster

The G23 has a tungsten rod with adjustable recoil spring and extended mag release.

Outside of a trade, what would you think a fair price would be to sell all of this?

I would really appreciate any advice from you traders!

Thanks,
Shane
