Hi Silverstreak02 +
I would check pinside-rating and ipdb-rating -> Look at the COMMENTS - I go for "playability" - art is fine - BUT playing is the fun ...
I would recommend a 1972 to 74 Williams or Bally - they are well documented (ipdb) and "rather easy to work-on" - Gottlieb-switch-travel is much more difficult do adjust.
Later models (1976) may have some gimmicks - more complex.
As others said: Do NOT hurry - BUT if one "grabs Yyou": Buy it.
(((OK - I admit: I happen to LIKE the Gottlieb-Drop-Down-Targets - so I have several Gottliebs - BUT: I prefer "working on Williams" , I decided "not to buy Bally pins - must I have spare-parts for Gottliebs, Williams -AND Bally ?".))) Greetings Rolf
