i'm also considering. high end records @ 25-30$ being conservative would take a sell trough of 500 records to pull it off but i'd like to keep those.

if i want to keep the 500 top records
Welkom in het gekkenhuis ;-)
b/w
A collection of that size will probably break down like this:
5% great stuff - obscure / hard to find stuff to salivate over. These are the ones you want to keep, but also exactly the ones you need to sell to pay $15000 for the collection
25% nice and semi-desirable stuff that "does" $15-$50 per title. These are sellable, but you'd either have to let buyers pay less than actual cost on shipping and/or profit from the fact that the $24 international rate from NL allows packages up to 2000 grams in weight
40% solid and clean copies of records that are not hard to find - close to impossible to sell these on eBay
30% unsellable chud
Personally, i wouldnt do it, but would try to buy the titles you truly want for a high(er) price and hook up a store w/ the rest.
