Not for me. Why?
1) I may not have much experience with full-auto, but it strikes me as a waste of valuable ammo. Unlike the Army, I don't get free re-supply.
2) Too expensive for me.
2a) If it's not expensive, it's illegal, and the risks inherent in having an unregistered full-auto are way too great to justify it for me.
