Giga Crusher worth the cash?

[1/18Mole]

I'm looking at several MTs (like the MF, MGT, LST, etc.) and I came across the Giga Crusher. Several people don't like it because of it's weight, some like all of it's power. Is it worth the $650 of the kit + $150+ of radio? Does it make up for it's cost in performance?
