Ok, so I've decided next year to do a project, but I'll need an accelerometer. Some qualifications include:
1. Has to be able to withstand a considerable amount of g's.
2. Has to be able to withstand a considerable amount of impact.
3. Has to not be affected by position (basically, if turned upside down it wont go all wacky).

Well, what im trying to do is measure the speed of a punch without rotation of the fist vs a punch with rotation of the fist. Thats why there is a problem with direction. Also, im looking to buy one that I just put together with a digital indicator. No idea about the 1 axis three axis thing.

So are you building it or buying it? Is it single-axis or 3-axis? Does it just provide a visual indication or must there be electrical output? A simple do-it-yourself single-axis device would involve a mass and a spring, and some sort of coupling to a slide resistor or potentiometer if electrical output is needed. But note that gravity is acceleration and will be measured, whether upside-down or right-side up, so it may well go all wacky unless you are careful to align it with the acceleration you want to measure.; e.g., if you're measuring longitudinal acceleration be sure it doesn't see any of the vertical grav. accel.

F=ma is true, but what mass to you use? the foot or the entire horse? The foot can have a much larger acceleration than the entire horse can, so it's somewhere in between. So I don't think the accelerometer would be very useful. .
