Hey everyone

hope things are going well.
Lately I've been looking over at my hobby area and feeling that theres too much to do! hehe.
Putting some serious thoughts into selling off rather a lot of the stuff thats there, and well, having a bloody good clear out!
Theres a shelf full of Dark Angels, with lots left still to build that is on the maybe list. ... lets see a quick(but by no means complete) run down is 25 or so temrinators, 2 dreadnoughts, 60-70 marines with various gear, 10-15scouts, 1 drop pod, 1 predator, 1 landraidercrusader (not built), 3 landspeeders (2 not built), 18bikers, 2 attack bikes,landspeeder vengeance, dark talon bomber, ravenwing command, converted ravenwing librarian, sammael on jetbike, azrael,
DV master,
DV librarian,
DV ltd edition chaplain, Blackreach captain, Belial... maybe some others
This army is largely magnetised and has option parts kicking around. Is partly painted in an alternate scheme... I could power on and finish it and then sell, or strip it clean and sell. dunno which would be better.
A smaller, but not tiny shelf of Skaven that could go to make way for something for Kings of War This is 80% painted, could strip it or not.. again unsure.
80 clanrats,
20 plague monks,
4 rat ogres with handlers
bunch of giant rats with handlers
screaming bells
few characters
4 weapons teams
A shelf of
40k Orks that I want to keep and expand upon

theres a blog for these in my sig

not had any time to work on them for a while though because of putting it all into helping the nephew with his Chaos Marines.
Basically looking for a little advice from those who have sold (or bought) mid to large sized collections secondhand. Am trying to consider what is a reasonable guestimate of the value, and the best way to go about it before proceeding.
