I have a Mystical Tome Stand(http://wiki.spiralknights.com/Mystical_Tome_Stand#Mystical_Tome_Stand) from when I used to play that is tradeable through steam. I got it from a moorcraft box during a black kat event some time ago and pretty much haven't played since. Because of that I don't really know the market value of the thing or care to bother doing conversions.
So my offer is this- 24 compendium levels(http://www.dota2.com/store/itemdetails/16410?r=c9) for the stand. It's a nice guild furniture with an active effect and I assume still fairly rare. Be aware however if you buy from the dota 2 store, it will be locked for trade for a week(at least as I understand it). Going to go with the first person who can make me a valid trade offer to my steam account.

Actually buying it off the steam market will lock it for a week too
