Value of a complete set?

What is the value of a complete set? When I say complete set I mean a set of all the cards. A complete set of each expansion and it looks like also the nergal deck, cultists, a&a storyline, promos etc. one every card ever printed. The Jyhad set in this collection also has close to 200 of the cards signed by the artists as well. If the price is right I might be willing to sell one.

Such a helpful group as always.

Ankha's answer was the right one. The VTES market's not big enough for most people to know definite answers to this kind of question. You'd be better off asking the people who run the shops on eBay (even though they'll obviously have their own agendas).
