Thanks for the info, the smallest "big" chip I'll be using is a 44-TQFP, plus other stuff like SOIC, SOT23 and 1206, plus I'm having boards made that will have solder resist so it sounds like it will be OK. I know there's a few threads about this around and nobody seems  to have too hard a time.

I agree smt/smd is not that hard just take your time and use a good solder paste.

with very fine pitch it can also be done by applying solder to blank board e.g tining pads, then once it has cooled down tack the chip with the corner pins then reflow/hot air, just use standard solder wick to get rid of any excess solder

I have also done QFN and LGA they are not hard but the alignment is more difficult

best tip given to me:
try to rest your wrist to help steady your hand
