Hi there Antiriad,
that's a lot of great gear you have there, and realistically you should put a price on the big items or "offers around xxx etc". There are several accelerators that have appeared for sale here today so maybe you should keep the fleabay option open or sell the items in bundles rather than having one big list, it would also be nice to see these items being posted rather than needing to be collected.
Everyone likes a bargain but don't feel pressured into accepting the first silly offer, structure the prices to something realistic or to what you are happy to accept while still being a bargain to the buyer.
Good luck with your sales
