If you can DIY, then absolutely go for it. If you are certain your distributor is the original, then you can DIY - the disassembly/reassembly is not difficult. If proper care is used, nothing should be broken. Do the work on a large sheet of clean, white paper. There are a couple of tiny C-clips, hairpin springs and screws which are easy to lose.

Setting the point gap is much easier to do on the bench than in the car.

Checking centrifugal advance is possible on the car, as per JW. Confirming the vacuum advance curve requires a tool, such as the Mity-Vac, about $30-40 used. However, since vacuum advance is not readily adjustable and OEM vacuum canisters are NLA, as long as it holds a vacuum, what you've got is what you've got.

Good luck.
