Don't forget a tripod.

Your budget is $3000
The PD150 is a very complete rig but it's $3100

The VX2K is 2350 at B&H. You may get it for $2200 elsewhere.

The picture is the same on both cameras, so is the lens and CCD block.

You will need other microphones regarless what you buy

VX2K $2350
XLR adapter $150

That leaves at least 500 for a tripod and some mic cables and a mic or mics. You will go over but this way you're starting at $600 less than the PD150 for the goodies fund.

If someone puts their hand in their pocket, then that's different.
