The PD150 and PD170 are very similar. The PD170 is the updated version of the PD150. The VX2100 is pretty much the same as the PD170 except it does NOT have XLR connections, which are the connection used for most microphones. I used a PD170 and I highly recommend it.
I don’t know what lighting advice to give you without knowing what you’re shooting. So, what are you planning on shooting?
