I bought a leon version a few years back to try and resurrect an Amazing Spidey.
system 80 boards, and under playfield parts needed too much, so never figured out how to use the tester
this new Marco might be a good investment as not too long ago I brought home a very nice HH sample game ( may be HUO ).
Also bought a quantity of every pin fuse known to man from CoreyStup here on Pinside.
I will most likely start a thread when I jump into HH.
Right now I'm just stocking up on parts supplies . . .
. . . I can hardly wait, as HH looks like fun, very different from my EMs and DMD pins
