PSP 32bit version I keep on my desktop because it has a twain interface and I scan a lot, and like you say it didn't break the bank

64bit programs don't seem to have twain, I think because there are no [reliable] 64bit twain drivers, printer/scanner manufacturers seem to have stayed 32bit by and large

but even then windows has it's own [fax and] scan software built in which I now find suffices most of the time unless I specifically want my scanner twain options

I had jasc 9 back in the day, ahead of it's time, but I never liked Corel PSP as an editor; affinity photo is good, there is of course a learning curve...
