I too used Greenback once. The truth is that if one has a relatively simple situation, e.g. salaried employee, then it is entirely realistic to do this oneself. With more complexity (other types of income like interest, capital gains,...) it can be more time consuming, but still doable.

I am not a professional, so seek and pay for professional advice, if that is what you need. I've been doing my own taxes as an American living abroad for ~a decade. If anyone is in a similar situation and has questions, feel free to pm me. Because financial/tax advice from strangers with no professional credentials on the Internet is always a good idea. :p
