these are the places from a US players point of view...would be different in Europe or Asia...like I would for sure add BritFoos
http://www.britfoos.com/ but i know there are many others
look at the end of page on Foosball.com/schedule and it will give you pretty much all the good and current ones i know of
http://www.foosball.com/schedule/here are a couple others i think that are relevant that aren't on that list...
http://www.insidefoos.com/Inside Foos...surprised its not on the list above but this is THE source for tournament video
http://www.minnesotafoosball.com/this has the foosball points book and database which will give you alot of the big tournaments in the past 10 years
http://fooslight.com/best foosball light made for the Tornado and Warrior and I bet if someone helped him with measurements he might make one for the other Euro tables
http://foosworld.com/public/main/players.aspxthis used to be THE foosball website and would still be if it had been kept up but the owner got too busy and it hasn't been updated in years but still there is a wealth of information...i have you linked to the old database and this has tournaments going back into the 70's...pick Todd Lofredo and you will see what I mean (and how great he is)
http://www.speedplay.be/profile.php?id=3&page=activityfor European tournament history...i have this at Fred because this shows just how dominant he has been for the last 13 years...totally amazing
