Micronauts and Microman discussion.

Well, since Yard Sales and what not are gonna be starting around here very soon, I decided I'm gonna keep an eye out for Micronauts stuff, since Microman looks pretty cool, but findng that would be very highly unlikely.
I found a website that's supposed to be the best( http://www.micro-outpost.com/mainframe.html ), but I was just wondering if there was anything else I should know.
For example, is the quality generally the same? Were there any major changes to the sculpts? Are they compatible with real Microman stuff and vice versa(as there were vehicles made specifically for Micrnauts), should I ever acquire any of it.
Also, a quick Microman question: There were two very cool looking cassettes that transformed into a motercycle and a helicopter. Judging from a commercial, it's obvious they aren't to scale with Soundwave's tapes, but are they the size of a regular cassette tape?
Sorry for the vaguness of my questions, but I really don't know much about Micronauts/Microman, and it looks like it's very cool to get into.
