This may have been mentioned earlier in this thread somewhere but for all new buyers I would STRONGLY suggest you add a Cliffy protector to the edge of the Munchkinland mini playfield. I ordered the whole kit right after buying my WOZ in the fall and held off on doing the difficult ones until it was time for the first really in-depth cleaning. When I went to take my mini PF I noticed that the clear is chipped off on the edge back over the RAI rainbow targets, thankfully it's under a metal ball guide so the ball can't contact it to make it worse and you can't see if when playing but the damage is done! I'm really kicking myself in the ass for not installing it sooner. Removing the mini PF looks daunting but it's not that bad if you follow the instructions in the manual, the only part that gave me trouble was making sure the wires from the spinning house motor stayed down through the hole when manipulating the mini PF into place. I would also recommend you replace the rubber ring on the "OZ" sling up there while you have the mini-PF off if your game has a good number of plays on it.
