We do 0603 and 0402 with IC's at .5mm lead spacing all day long. Under
stereo zoom, it's not an issue. We have 50+ year old techs who build
this stuff all day...
We have one of these on every bench. At around $700 new for the 3x to
90x Zoom it's not bad. But may be prohibitive for home use. I can
highly recommend adding a .5x bottom lens, as this increases your
working distance by a factor of two...

Once you go surface mount, you'll never want to do through hole again!

I bought a stereo microscope some days before and I agree with Bob. I
keep building non-RF projects the classical way (through hole) but if it
comes to radio frequency I prefer SMD since high frequency is easier to
handle. Can you tinker with the idea of buying a stereo microscope? It's
absolute fun to easily solder those miniature parts!
