Sure, there are 3 reasons to add on '040/'030 mac to the mix.
1. Much much faster. It will decompress the files for you so you can copy them - uncompressed- to your SE via localtalk.
2. More RAM and disk - most 040s you will pick up will have 8+ megs and 200 Meg hd, making the decompression and storage much easier.
3. They are cheap. Get the cheapest you can find- you don't care about collect-ability just that it works.
Also, a suitably equipped '030 would work as well. You just want something that can run say 7.5.3 or 7.5.5 and do all the decompression for you.
Perhaps Ebay is not the answer- in that case, Craigslist. I see a LCIII near me for $40. Yeah, hmmm, the prices on Ebay are crazy.
