Quoted from misterhare:
I was considering the Wolfpac Tech orange for my crummy displays, but I was intimidated by the soldering. What do you qualify as "basic soldering"? How long have you been soldering?
I've been soldering for a while, I do some board repairs, I've done playfield swaps, hardtop installations, etc. That being said, the kit is very straight forward. All you are basically doing is inserting components and connectors through the holes in the circuit board and dropping solder on each pin/hole. It's more tedious than anything but slow and steady wins the race. A good soldering iron definitely helps. I have a decent Weller with with a temperature adjustment but I did three playfield swaps with a cheap, crappy iron (not recommended).
I've installed them in my BK (red) and SS (blue). Personally, if you are going to update yours, I would seriously consider the blue ones. Picture doesn't do them justice...
