It's not hard to find a synth that retailed for 2 grand going for 300-400 bucks. Yet much old budget gear is very frustrating to use, especially the early digital stuff. You'll be limited. Limitations are not necessarily bad. Today we are rather unlimited.
Limits force one to think of work-arounds and alternate ways to get an audio result.
In the right hands, even older, average gear can make great music. It is your interaction with the machine that makes the good buzz. Yet the latest gear is friendlier than ever, easier to play on. In modern synths for example, you will find hundreds, even thousands of instruments all tweaked and ready for your specific applications. If you want drums for Techno, DnB, Hip Hop, Country, Orchestral, you'll find them all in the box ready to go.
