A friend of mine told me a great life hack. She said to poke the Allen key through an elastic band or a condom while inserting it into the set screw.
I tried the trick on one of set screws on my 688. It works like a hot damn. Less wobble.
I've been using a Craftsman rotary tool that's a rebranded Dremel for about 15 years.
Accessories that I have are the flexible remote shaft system and the drill press for pc boards. The only problem that I've encountered are the brushes wore out and they were easily replaceable.

I've been using the maha c-800s for years. Slow charge the batteries when they get used and once in awhile I use the reconditioner charge mode.
Batteries and charger are cheap and easy to get

I've replaced the switch. Bought them from Lectrosonics 1-2 dollars a piece.
You'll need patience, a soldering iron, solder wick and a sucker.
Take pictures as you take it apart, mark the screw locations and go slow.
Good luck
I've bought coax with Sma ends in computer shops before. You have to be careful sometimes the connector has the reverse sma on it, meaning no centre pin in the connector.
Also I've used paper clips.
Good luck to your buddy
