Whatever venue you use to sell on,,I would search and see if any items like or similar to yours have actually sold !! And don`t put too much faith in online appraisals !! What you want to know is not what an item may be worth if you can find a buyer,,you want to know what they are selling for right now !! If it were me I would price items according to what I had to pay for it plus any costs involved then add a reasonable profit. If your prices are lower than comparable items are started at,,you get more sales/bidders and stand to do well !! By keeping prices lower than the other sellers and actually selling items rather than putting a price that is above what most are going to pay,,given this economy, you will come out ahead and will move more of your inventory !! People will stop looking if your listings don`t change pretty fast !! Think volume !!
