@capslock... don't worry too much about the complexity of the rebuilding the pops, it is actually rather easy... the only pita part is soldering that dadgummed light socket... other than that, just follow the steps described on pinwiki, and you will have it apart and back together again in no time... ime, rebuilding my first pop was easier than rebuilding my first flipper... with the exception of the socket of course, i cussed at that thing mightily before finally getting a good joint... but i am quite possibly the world's worst solderer...
note: pop rebuilding, like a lot of other things, is easier with the playfield out of the machine... furthermore, if you are even thinking you'll get another machine down the line, building a playfield rotisserie is "worth it"...
