I doubt whether Beseler would make a junk timer. I use the Beseler timer 8177 which is the same timer in every function except that the time is set with dials rather than digital numbers. I suppose the digital number part might be less durable than the dials but I think it is pretty simple technology so not something to worry about. The part that wears out on the Beseler 8177 seems to be the switch from X1 to X10 and the start button. But that doesn't happen till after many years of hard labor. I am on my 2nd timer in 20 years of daily printing but the original foot switch still works fine.
I would say that 50 dollars for the 8187 is money well spent if it hasn't already made 100,000 prints
