It looks like all of these topfire sticks fall off the radar. I am wondering if they get too expensive of what.
i've never used a top-fire, but they just seem cumbersome to me. they don't seem like they'd be very good for trigger games, because your thumb is not as agile as your trigger finger. and you can't grip the ball top when you're pushing the button, so you have to grip the thin metal shaft.
they also don't seem like they'd be very good for non-trigger games, because you have the button sticking into your palm.
i've always thought of them as a compromise made to save money, rather than a really good solution for any given application.
i think the happ 8-way flight stick is the perfect solution, although admittedly expensive. and it is the only solution, as far as i know, if you want to play discs of tron, which requires both a trigger AND a thumb button.
the tron cocktail seems like a decent second-best, because it appears to work well both for trigger games and as a plain joystick.
