It is a pretty complete package that's well thought out for someone who just has a stock A2000. The CD rom and 4gb scsi drive and cables would cost a bit on eBay. There are lot of sellers that try to get outrageous prices for old drives. Mostly they don't or wait a long time for a buyer. 250mb SCSI zip drives are a good example. Because there is a lot of old Akai and other music gear that can use them, there are usually a lot listed for around $70-$100. The same drives keep getting relisted. I've bought 2 over the last few years and I paid around $30 shipped for each of them. Now that eBay has a sold listings tab, I see that most that have actually been sold have gone for $20-$40 and the overpriced ones do sell but not all that often. It can take a bit of patience to find a good SCSI drive for a reasonable price on eBay. I used to get them from old Macs from our recycling center but now they won't let us local people take the abandoned hardware people leave there and instead send them to an electronics recycler that pretty much does the same thing with pulled parts. They aren't on eBay but they try to sell stuff like an old AT power supplies for outrageous prices on their website. I did get a good supply of SCSI drives and 72 pin simms while it lasted.
