Steiner Binoculars value

[Broadsword]

I have a set of Steiner bino's I'm considering posting for sale or trade. They are model #539 7X50R/LPF with M22 reticle and laser protective filter. They are in the original box w/ strap and have been used in the back yard about three or four times. No field use.
Anyone have an idea what I should ask for them?
Thanks,

samplelist dot com is somewhere I have bought a lot of optics from. Right now I believe they have your model for just under 500. I bought the M22 three years ago, and paid a lot more than that for it - the price seems to be dropping, I imagine the saturation point has been reached for this set of binocs, besides, they're HEAVY!
