I've been tempted to buy one of the bundles over the years. The feedback amongst it's users seems overwhelmingly positive.
I think what stopped me was the fact that you may need to purchase more 3rd party libraries depending on what bundle you get and what your needs are. (like what kind of FX emulations are you looking for.)

The CM magazine edition has some nice demo patches to check out. I'll probably PM you a link after I dig out a CM DVD.
