Taking your questions briefly:-
1) Yes
2) Unlikely
3) Choose kit that you like working on
4)
DeptsNotes:-
1) But not so much in recent years
2) But other potential customers are available (
eg, vets, small repair companies,
etc.)
3) It doesn't
have to be medical equipment!
4) If it's out of date ... better let Huw know!

At the end of the day (there's a meaningless phrase for you) you need to make up your
own mind about all this stuff. Another bit of advice I could offer would be:- why not take this opportunity to ponder what it is you
really want (or perhaps, need) to do ... and then follow your star!
