Small quantities of parts can likely be sourced from foosball australia or the nwfoosball seattle group. I have both tables and I think the Fireball coinop is a more modern design, better build quality, and improved playability overall. For home it has some very convenient benefits and it is awesome, it is also good for promotional use. However, I would not put my fireball in a bar or public venue for many reasons mostly due to parts/damage/theft.
The Warrior is a midrange table, excellent for its price range and casual recreational use... however the tornado tour/coin or fireball tour/coin are significantly better tables. Shelti is a close third.
Most everyone here will suggest that if you wish to pursue North American competitive foosball, or attempt to dominate at your local bar, the Tornado coin op is the best choice. Coincidentally, Seattle has had quite a few older coinops in craigslist the last couple weeks in the $650 range. This is an opportunity if you don't mind an older table that could use a couple upgrades and a rookie to keep it busy.
If you are in the Vancouver area be sure to join the scene cause we would love to have you out... Vancity foosball DYP PRO/AM, Vancouver foosball Addicts Beginner-Intermediate, Soho Billiards drop in Wednesday Friday. Also Seattle is about to have their yearly Fireball tournament next friday if you wish to see the Fireball Foosball in action. Bank shots, euros, and backpins all around...
