I free type the info from the SP Certificates, I guess that makes it look like I've made it up but I haven't. The majority of people in my tree are Scottish so I have a lot of data from SP.
I also type the details, including the reference (District/year/RD/No - so any future researcher can easily follow it up) directly into my notes.
When I started out with this 36 years ago, this was the only way to get information. There were no digital images or computerised indexes, so you just had to find the certificate or census and copy out the details.
You still have to transcribe information from births less than 100 years ago, marriages less than 75 years ago and deaths less than 50 years ago, so it is not possible to get either digital images or print-outs of all certificates and censuses anyway, so I didn't see the point in collecting them. (Couldn't have stored tens of thousands of sheets of paper anyway!)
And if I did decide to go back to SP and download images of all the post-1855 certificates available for people in my tree (7521 births, 5163 deaths, 2484 marriages) that I have already seen it would cost me well over £22,000. And that is only for Scotland, and doesn't include pre-1855 baptisms and banns, or any of the census.
I don't think that reluctance to shell out that sort of money for information I already have to hand is 'stingy'. I'd rather say 'prudent' or 'thrifty'

It didn't cost me anything like that, of course, because not only did I collect much of it in New Register House/Scotland's People Centre, but in the good old days it used to be possible to make an appointment with a Registrar, and be let loose in their strong room where all the books were stored, and just leaf through the book and make notes (in pencil, of course). That is no longer allowed. You have to be supervised at £20 per hour now, so it's much cheaper to use an SP centre at £15 per day.
