Aye. My Rotel system + Infinity speakers are ~20 years old, and even does beautiful 5.1 multichannel through the HTPC after finding a DB25 to RCA cable with my Asus Xonar Deluxe soundcard. I had to replace the baffles on the Infinity speakers after the first decade; sound is just as good if not better than when I bought the system (thanks to that Xonar card).

A few months ago our 11 year old Nilfisk vacuum cleaner broke down. Back then it was about A$450. Instead of buying an equivalent new one for ~A$700 or so, I repaired it for ~A$250. I figured it'd still be better than buying a new $200-300 vacuum every 2-3 years.

Sometimes buying expensive stuff is the cheaper option.
