An extra jet pack without making the bust look ridiculous would require much more of his chest and abdomen as Darth Waller has illustrated very effectively.
Also, if you think it would only have cost an extra 100 dollars to include a jet pack that size, I need to start smoking the same crack you are cause mine is obviously not as good as yours . . .

personal attacks aside (I thought you were above that stuff from the quality of your other posts Dennis) my point is that forgoing the electronics would save, say $100, and adding another $100 would make the cost of the jetpack and maybe more of his chest about $200 total.
heck, even make it $1200 for a proper fett bust and I would still get it. of course just my opinion...
