It's good to see someone budgeting for the chair!!! It's so overlooked!!!! It's the MOST USED EQUIPMENT in virtually all studios
Regarding synths and the virus and hardware and so on, it's important to realise that you quickly get into pointless debates about the merits of hardware vs software. You'll find yourself on one side or the other eventually. Ask yourself, are you a playable musical instrument person (piano, guitar, drums etc), or are you a computer engineering/programming type person? I do enough of the latter at work, so when it comes to music i want it as hands on as possible, which means hardware for me. The limitations that the hardware impose actually make me more creative. I think software is too flexible, and does too much, and I end up spending time configuring and tweaking and doing tiny little edits and tweaks and getting annoyed with how something is implemented etc etc
For me, the process of creating music is just as important as the music that is created. So I value anything that I think is fun to tinker and play with, and twiddling with hardware just gives me orgasms.
Dropping a bunch of money on a synth is a commitment of sorts. You can get away as a total cheapskate by downloading cracked soft synths, but when you drop cash on hardware you generally tend to want to get something for that cash, and so you end up putting a lot more time and effort into understanding and really pushing what it can do. Getting cracked software for free, in other words, can mean that you do not value it. Easy come easy go. You can easily get caught up in searching for the perfect synth, and just download hundreds and hundreds of things. Sticking to one is great advice (hardware or software) but its a hell of a lot easier to stick with one hardware synth than a software one.
Personally I wouldnt bother with Komplete. Its too big and general purpose. Just get a cracked copy and use the money to get a second hand synth instead. Play with both for a few months and then sell the synth. You'll then be in a good position to decide what to do next.
