I heartily recommend batch-selling it on eBay in units. I know eBay cops a lot of flak and listing individually can be a ball-ache, but it's still the easiest way to shift your collection and you only lose about 12%-13% in total fees (no Paypal fees on top of that any more). Your prices may well be a bargain for what the buyer is getting, but not many people have that size of wedge to spare in one go. I've been selling off a mate's 15mm armies for him and they get snapped up when listed in units for around the £25-£50 plus postage mark.
