we are looking for the best possible fooseball table out there. we arent really into any fancy woodwork but just a well performing table.
Andrew,
Where are you located? I'll echo some of the other opinions: Garlando, Bonzini, and Tornado are the dominant tables for tournament play in North America, with Tornado being far and away the leader in the US (and big in the UK as well). Garlando is popular in parts of Canada (and in Austria/Italy/parts of the UK). Bonzini is popular in parts of Virginia and North Carolina (though Tornado is popular there as well), is spreading south, and is popular in parts of Canada, notably Quebec (as well as France).
I like to analogize with tennis.
Tornado is like the hard-court game, mostly about speed and power. It uses a hard urethane ball that has a fuzzy texture, and has plastic men with medium-width feet. There are 3 men on the goalie rod (so no banks in the corners) which argueably helps you set up the ball for goalie shots. Sliding push/pull shots are common. Banks are tougher to execute, but high-speed brushes (like shot recoil) are easier to control than on most tables.
Bonzini is like the clay-court game, lots of control. It uses a cork ball which is very different, you gain a lot of "grippiness" and can move the pinned ball around a lot but it's much harder to shoot sliding pull/push shots (you have to have the ball in front of the rod to do them effectively). It has metal men with narrow feet--narrower feet increase scoring from goal and make it really quick to get around the ball on pin shots, but make catching harder and make kick shots tougher (as well as making defense trickier).
Garlando is like the grass-court game, very much about speed and historically the least grip of the 3 tables (I haven't played on the new generation which supposedly improves this some). Medium-width feet, plastic balls, blasted glass surface.
The Shelti is an oddball, similar to a Tornado (3 man goalie, etc) but it is a grippier table (which helps catching and pin shots) and very wide feet on the men (which makes pin shots tougher but helps push-kick/pull-kick shots and defense). Overall pin shots are easier than on tornado. If the feet weren't so darned wide it'd be my favorite table, play-wise.
As it is, I prefer the Tornado style of play but they all have their good points. I would probably get whatever table is used for tournaments near where you are so that once you've practiced some you can go see the good players in action and take them on.
