i'm a 100% supporter of ebay b/c it puts your products at market price (if not more).

seller rating isn't a big deal as long as you dont screw it up. everyone has to sell something for a first time (then it never ends...)

I've been selling used music gear (PA equipment, mixers, cables etc) on ebay for the past year and it has only been kind to me in giving me a price i feel the products are worth.

craigs list, due to reduced demand, drives the price of your used goods to maybe 25% of the original price rather than an ebay auction, which will push it to 50% or more.

I would list this in the "for sale" section of the head-fi.org forum. It might get some interest if the price is attractive. Lack of feedback there didn't seem to be a problem when I sold a Grace m902 headphone amp.
