We also specialize in expat tax.  I know what you mean about those practices... and Block.

I would strongly suggest that you give PTO a try for the few international returns you prepare.  Sign up for a trial and replicate those returns you prepared.  With Lacerte under the hood, it's much much better than manually preparing those international tax forms.  It's not perfect, largely because PTO lacks the nice-to-have features in Lacerte, but it gets the job done.
