I really like mine too, seems like the more I play it the more fun it gets..
Currently I have it here in the break room at work, it seems to get more play than my Radical that sits next to it. However, it seems like the more "advanced" players work their way over to Radical after getting pretty good at BG.
No mods really, just LED's in the back box and some in the play-field for good effects. Definitely a good solid machine that doesn't break down too often.
