You know, you say you can afford 2 machines. If I were you I would get a MonoMachine and a Machinedrum UW.

The Machinedrum UW offers sample recording unlike AR and a lot more sample manipulation. So right there you have a solid mix between AR and OT.

Monomachine offers a TON of sonic flexibility, you get similar analog sounding engines without it being of course analog plus wavetable, Sid, FM. It’s not a purist’s analog but at least you won’t go digging elsewhere when you need some variety in sound. And plus it allows to upload user waves for the wavetable synthesis.

With these two machines someone would have to really twist your arm to get more gear for a while.

Of course it all depends how you feel about this whole analog vs digital business. But I tell you if someone offered me MD UW and a MM for my A4 and AR I would not hesitate to trade.
