If you like the guitar and enjoy playing it, stick with what you have. The replacement might not play so well.
I love my asat special but didn't like the Dadario strings so switched to my favourite same gauge EB regular 10s.
They all work mostly the same, buy a cheap one every couple years or an expensive one every ten. Mine was expensive as I need it to do a lot for work. A quality resistance, capacitive and voltage multimeter around £20-£30 will be ok.
Wanted a slightly more driven overdrive pedal than my Chevtone Honeyburst. After much searching found these fairly locally from a company called Vein-Tap. It does a clean boost very well all the way to fairly heavy metal sounds. So far love it although the led is too bright😎
A lot of their pedals they have just completely copied the Boss pedals internals so they sound exactly the same. Plastic cases which doesn't bother me as only play at home and at less than £20 a pedal I can buy one and just give it away if it's rubbish.
