Scrub my previous comment about this being a friendly community.
I offered an answer to the question posed by this thread. There was no obligation for that answer to be friendly, specifically, but if you actually found it hostile, you may want to grow a thicker skin. Ultimately it's not my concern whether you find my comments, or this community as a whole, to be friendly, though, so do as you like.
What I meant was that out of the box (or whatever they arrived in), for example my plus and classic 2 don't have any network interfaces. It is possible to buy SE/30 ethernet cards, SCSI to ethernet adaptors, but what I am finding is that anything apple branded be it a mac plus mouse or an ethernet adaptor seems to command a premium on ebay (and ebay seems to be the only place to obtain vintage apple gear locally unfortunately, and not even counting the usual postage which internationally can be expensive).
Try posting a WTB on the
LowEndMac Swap List or the Trading Post here. I've gotten some good things off of eBay, but swap lists and forums tend to be more effective and cheaper (and people tend to be more flexible about shipping, which sounds like a major concern for you). There's no getting around the fact that old computer hobbies cost money, though, and this particular one will probably get more expensive as time goes on.
