1 Jawhorse or 2?

[Jeep07]

All my sawhorses are shot so its time to replace. I'm intrigued by the JawHorse and I'm wondering is there a reason/need to buy 2 or is 1 good enough? I'm used to using several sawhorses for projects but this might negate that need.

Thoughts?

I have one jawhorse and I believe one is fine.

I like it but they are a bit of a pain to move.
