Soon I realised though, that support from the user's and the company themselves was key in providing some guidance on how to get the best out of the units and also that magazine articles and video tutorials seemed to revolve around comercial products for obvious reasons. they also guided me in my musical ideas. It was then that I started to notice the different and harder types of synthesis like FM and Granula Sampling, needed that kind of dedication from the users and ther company to help me realise my ideas.
Lately their seems to have been a flury of vst releases of anologue subtractive synths, that blur the lines of what can be found for free and what should be paid for, it's a difficult area but one that is completely down to what I stated before and working preferences like GUI, Possible Modulations and overall sound quality.
With effects however, sometimes their can be slightly less to worry about, DBGlitch is still in my folder and I can't see it leaving, as it still can do pretty much everything the other paid for versions do, if you choose some host modulation.
Certainly you should consider if you can get away with not replacing you trusty freeware folder with a comercial version.
But remember, the company's themselves debate long and hard about a potential product, so it's worth demo'ing new and older gear and doing some A/B comparisons against freeware alternatives, just to see how it will perform under the kind of pressure you think it should.
I reckon you may eventually see the likes of NI Massive and FM8, Camel Audio - Camel Space and Alchemy begining to seem some how filling a lot of different roles and worth the spend.
And I'm sure the rest of the guy's here on the forum, will agree buying a spare or unwanted licence from them here at KVR or E-Bay is a much more professional attitude towards the comercial music environment than anything else you might consider.
I saw a post on the Ableton forum for a guy who's selling a NI Massive licence for £60.00 today, that's very helpful to someone starting out..
