Figure Sales — Community Recommendations

I am pondering putting some of my various spare, mint figures up for sale (time to turn the investment — what I got the extras for, after all).

Since this community is the obvious target market: any preferences/recommendations for sales method?

(In regard to the classifieds and auctions, I am open to recommendation for good sites — I am not very familiar with the best, preferred ones for listings of this sort of merchandise, outside of eBay.)
