It all depends on what kind of fun you want to have.
I haven't heard your piezo transducer IRL, I wonder if it is nice like my 386 and old computer speaker set up.
I think cost is at best a secondary consideration, given the value of time, a perspective that will surely change as one ages.
We know the @anon57585045 is 60++ (61? 
) not being pessimistic when I say more years lived than remaining… I too am in such a place. A little further along, never mind precisely how much further.
Nevertheless long habits of finding the cheapest way to solve a problem no matter how long it takes to do tend to mask the real cost - I often refer to my $180 this or that what I might have just trashed and replaced instead of spending precious time fixing.
