If you look on Ebay under Outdoor Sports, then Hunting, then Reloading, then 'Reloading Presses' you will find the same model PW's and that should help you with pricing....the 'sold' price for each model etc.....accessories are usually sold separately....
Ebay is also the best place for you to list these items and receive the most buying traffic and the best sales price, as the buyers fight like children over this stuff......
Once on the Reloading Presses and Accessories thread, you can key the search window at the top for Ponsness Warren, just looked and there is a model 800C .410 set up listed with 4 + hours left at this time and has 17 bids at present.......
Best Regards,
