When you say "swap pages", I guess you mean the Knife Edge software forums ? I saw people sharing many models on the KnifeEdge.com forums.

Some people back home have been getting the expansion packs from torrents, but then that is illegal

There are also all-in-one simulator packs on eBay, which seems to carry all the expansion packs.  Again, not sure about the legality of it.

Many people are going for this now, as they are wireless !
