With sales going live on the website tomorrow I would like to post a couple of suggestions for anyone interested.
If you have upgraded speakers in your game, be sure to read the section on the website about them. The upgraded speakers work great with the light kits, but you MAY need the longer screws to mount them.
I also suggest if you have stock speakers and think you would EVER upgrade your speakers....go ahead and order the longer screws. The style of speaker that Pinball Pro and Flipper Fidelity are both selling at this time need the longer screws. These screws are a hard to find size and I have never seen them in a hardware or fastener specialty store. If you might have a speaker upgrade in your future...paying the extra $1 to be ready is a safe bet.
My next suggestion is to try out the different mounting options if you buy an acrylic set for the light kit. It is surprising how differently the different mounting methods look with various acrylic sets. I have my Black Spider-Man mounted the standard method with the acrylic on the outside. I have my X-Men with the acrylic behind the speaker grills and I prefer others (like Family Guy) mounted with the acrylic, then the light plate and then the speaker grill and speaker. The kits are easy to install so experimenting to see what you like best is a breeze. I actually had one of my X-Men on the inside of the grill and one of the outside for a couple of days so I could decide which way I liked better.
