using bay isn't all that bad. You'll end up losing 13% after fees though, so you'll have to calculate that in. I'd just check what auctions are completing at vs buy list. If they're within 15%, ship to the buy list. If they are way less then take the time to list them for auction. You should be able to move a bunch to buy lists w/o losing that much and just end up saving some time.
You can also use magictraders.com and sell through there. Pricing to sell on there is usually right at/under auction prices to get people to buy them. You typically can get buyers to cover paypal/shipping as well. If you have no feedback through MOTL, you'd have to be comfortable researching the buyer's reputation and 99% of the time sending first since you wouldn't have a reputation there. You're required to set a price, so it does make things easier when you don't have to worry about what price you'll get. You either get your asking price, make a deal that you're comfortable with, or just move on.
this is what mine looks like if you go this route. I sell regularly through MOTL:
