They are 'poor mans omnis'. I'd like to get away from using them too, as are heavy.

Now, don't automatically go thinking that a lighter chassis is a better chassis.

I explained in another post that having a relatively heavy chassis isn't always a bad thing. It basically forces you to make a lighter manipulator, basically meaning that your CG will be closer to the ground.

For the past two years our chassis (...I've never used the plural form of chassis) have been in the range of 80-90 pounds. We haven't tipped once in those two years.
