I'll give you a useful reply as someone who HAS sold and occasionally DOES sell used laptops on eBay. From 2004 through about 2010, a company I co-owned sold thousands of laptops on eBay. Selling conditions were slightly better back then. I wouldn't consider selling nice laptops here anymore.
Any laptop that you believe has value selling as an individual laptop for a fair price should NOT be sold on eBay. First, good laptops are a target of scammers. Second, if you have 300 laptops, you are not likely going to have time to test them in real-world use like a buyer. Used laptops cannot be trusted to outlast eBay's buyer guarantee. The two most common issues that can escape your best efforts of quality control are fans that fail or become noisy and batteries that either fail or simply don't meet buyer expectations. I have seen hundreds of laptops over the years that appear to have good batteries, but during use will work their way down to some random percent like 62% remaining, then the laptop shuts off.
INADs, scammers and whiners are not worth the time, wasted money and frustration to sell laptops here. I don't know what the local market is like in Omaha, but here in Pittsburgh, good laptops sell locally just fine. I price them on the low-end of what someone could find it for on eBay, but there are no fees, no shipping and no returns.
As for laptops that have problems, those sell fine on eBay in lots. I like selling lots of 4 because the weight and box size and packing are easy for 4. I recently sold a lot of low-end laptops, item# 305149887537 in "parts or not working" condition. The format of this ad has been effective for me.
You used to be able to list lots in auction format and buyers would bid them up to great prices, but that seems to have died right around the time eBay claims to have eliminated bot views. Now, just do a BIN for what you want or high BIN+offer option. If priced right, they will sell and the buyers tend to be decent.
