If I may, I bought the Factory bundle and have been very happy with it. The Waves and Bomb Factory plugs, as well as the Digi D-fx set, are all top-notch. I used the D-Verb for a while, but I got RealVerb later and have used it as my main reverb ever since. The NI Dynamo is usable for some applications when you need a pad or weird sound effect, but it's certainly not my favorite soft-synth. Overall, the extra $400 you pay gets you a load of good extra plug-ins that you would have to pay much more to add on to the regular 001 set. Of course, you can always add on as many as you want from there. Hope that helps. T.
