BEST Ab equipment?

[Toff]

I get really dizzy if I bend over or lie down, or invert - no idea why, just happens, roller coasters etc all make me real dizzy
.
What Abdominal equipment out there can help with abs but not have me inverting or using a roller?

Something that i can add weight to as i never develop abs (ok fatloss needed too)

Pull ups, squats, and a clean diet. Ab equipment is non essential, and you can have great abs without them.
