where to get Factory Shop Manual CD
 

I'd like to get a FSM CD that covers at least the 80s-90s W124 E-class M103/4. It would be nice if it covered 90s-00s W210 E-class as well. I'm particularly interested in diagnostics, electronics, specs and special tools. Maybe someone could tell me:

Where is a good source for these (besides ebay)?
Do the CDs cover multiple chassis/classes or are they more specific?
IMPORTANT!: Will they run on a MAC computer?
About how much do they cost?

I would consider used ones if anyone has some they don't need anymore.
Thanks

No 124 available at that site Kent.

None of the Mercedes software work under OS X, you'll need to have a Windows partition and something like Bootcamp, VM Fusion or Parallels.

I got mine from www.mercedesmanuals.com

Check your PM's.

Thanks for the responses guys, I appreciate it.
Having a MAC can be bit of a problem this way. I bought a VADIS CD for my Volvo S80 from some schmuck on ebay which didn't work (got a copied DVD instead of the "genuine" item advertised and it wouldn't open at all on my MAC like he told me it would). Even a computer programmer at work couldn't get it to run on his blitzed-out monster PC. So I need to be sure whatever I get will work before I buy it.
I'll check the sites you guy posted so far. I'm a die-hard MAC user but I guess I could borrow my kid's laptop PC if I had to (I'd almost rather ride a bicycle!, almost).
