Several colleagues of mine have moved to Argentina for varying lengths of time. Most of them have enjoyed living there once settled in. But the settling in process, everything from immigration to basic services, can be a nightmare. Having an Argentine wife will no doubt help. That said, the advice from my colleagues can be summed up very briefly as "be very very patient and very very persistent". I might add, hopefully you don't need to work for a living for a while after arriving, as you'll be very busy taking care of simple things that in Argentina just aren't that simple.
