Can you suggest a fair price for these ELMAs

[warpie]

I have a few of them and looking to sell them as I need to fund other projects.
Does anyone knows what would be a fair price to give them?
I got them with a trade deal so I have no idea how much they cost.

Farnell has the single deck version but mine are 2-decks.

They seem to be identical but with different colour.
thanks

Nice switches, high quality...although I don't think you'll be getting the Farnell price, even though they're dual deck.
