What is SSW?
(Sorry, I'm not into acronyms.)
Anyway, here is an EBAY Auction that is an example of the type of pricing I was talking about above. Mac128's fetch more than other compacts in that era simply because they were the first Mac made. And this particular auction is selling for a high price because of the great conditon -- which is somewhat rare. Most old compacts were left in front of a window for years or otherwise in an environment that caused rapid yellowing and deterioration of the plastics. The better the Mac looks on the outside, the more it will sell for, regardless of whether it was an ultra rare Hyperdrive in it. That's not to say the Hyperdrive has no value, but it's best to sell that value inside a pristine case!
You can also find other high dollar compact Mac sales on EBAY from time to time. Dan the Apple Mac Man is one seller who offers only premium grade machines, often in complete sets. His sets are so complete and plastics so clean that he often starts out pricing at $700. I've not see to many that are selling for that price lately, but I did a few years ago. Pricing does fluctuate though. It depends how many classic Mac lovers are trying to big on the same item at the same time.
Money aside, I love my Hyperdrive Mac because its so rare and its still useful. It's fun having a Mac do something it really wasn't designed for (unlike the SE series which accommodated an internal HD).
