I’ve never bought anything from craigslist,but I have bought several dvd-rw drives from ebay, as well as my used Epson R-300.
1 Plextor PX-716A for around $75,works great,but not like my 1640s.
Then looking for another drive for a buddy a couple months ago,I got a Plextor PX-716A for $40. After I clicked pay,I noticed the seller had a really high number-power seller-a very bad move on my account… Drive was DOA and had to go through the long process of RMA. They refunded all my money,but I was still out $7 for shipping.
Then I found someone selling Benq 1640’s,and bought 2 with the discounted shipping- $37 each. One went to my buddy,other is stored away for later. Test burned both drives and scored mid 90’s for Ritek-P16 media. Original seal still on them.
What I can advise,stay away from the power sellers. You’ll notice how they have 10 different sales on identical drives,with the identical picture. Those are often Refurbished or have no clue if the drives work.
Look at the sellers with high positive feedback,not so fancy listing,and under 100 for their rating. Less chance of getting refurbished equipment. A lot of those smaller ebay sellers think they are upgrading to newer drives,when it looks more like they’re downgrading.
I still keep an eye at ebay for them in case I run into a bargain. I’m batting 75%.
