Oh shoot! I forgot about that.
Hmm, well I own one of the old Apple Modem 300's for my Lisa and I know about the Apple Personal modem but it's not to the Mac II style.
I remember I had one modem way back with my Mac SE that had that Mac II look to it and even had serial passthrough. I have not seen another one since I included it in a trade with my SE for a NeXT cube but I do still have a picture of it.
Reardless of speed, that would look perfect.
I'm not really interested in buying more NuBus video cards (sans for the GC I guess). I already have a mountain of them and I didn't say I wanted to make an Ultimate II system. That would cost a blommin' fortune for some of those parts and so far the total I spent on everything I listed has cost me under $100. I know the higher end Radius Thunder cards can still fetch a bit of money. Photoengine cards are also dirt cheap ($25 each I got my two).
I do also have one of the 10/100 network cards but I find that a bit of a waste on an 030.
