Yikes!
I'd hate to see what your takes on "fair use" is. You guys work for the RIAA by any chance? lol.
If I buy it, I own it, I can do what I want with it.
That being said, I'm not a huge fan of most mods, but I like some, and I don't really like LEDs. I have one game with a few in it, but I'm working on emulating standard bulbs (Looking for longer life and reducing the power-draw... not making pretty colors or blinding whites).
However, if someone wants to light their pin up like 30 Rock at Xmas, to the point of needing to wear a welding shield to be able to stare at it... good for them.
Its making them happy. They aren't hurting anyone (expect maybe their own retinas). They aren't "ruining pinball" for you, are they?
I think the extenders are fine. Use them as "training wheels" until you get the hang of the game, or keep them on forever so you and your guests can ENJOY the game more.
Its all about the fun, right? If you think mods are fun, mod away! LEDs? Go for it! Lane extenders? Why not? You want that table at a 2 degree angle? All the more power to you! Toppers? Put a freaking 61" plasma tv up there with the movie the pin is based off playing on a constant loop if you want!
Support pinball in all its forms! Don't bash someone because they enjoy the hobby in a different way than you do. We can all enjoy it in our own way.
Some people compete, and want tables at PAPA difficulties. Some are happy to just bat the ball around to have some fun and relieve stress. We cant say that one is "better" than the other. Pinball is pinball... and its all good.
Not trying to start a flame war here, just putting in my 2 cents. Plus I suck, so anything that makes the game more enjoyable is a good thing... to me at least.
Keep on flippin'
