Real analog vintage synths are a lot more expensive and difficult to maintain.
Virtual Analog synths I've mentioned are quite good sonically and are pretty basic. Most models' I've mentioned are discontinued actually but a lot easier to find and maintain than any synth with analog filters and oscillators. Also, you've mentioned arpeggiators and how you like to use them and well... not that many true analog vintage synths have arpeggiators. If they do they usually cost the big bucks. Usually that is.

DSI Evolver uses both digital and analog oscillators and has analog filters. You might want to check that one out as well.
Korg Legacy collection synths are certainly worth checking out. But only if your computer is up to specs.
