Also there's mention that the bucking doesn't come with the PDI, so I'd have to invest in that as well.

I'm looking around and doing more research, but looks like the PDI is a decent upgrade for me
Here's what I've got in mine.

I've got an Angel 6.03 650mm Tight bore for PSG-1
PDI hopup chamber
RH75 hop bucking.

It's turned my some what accurate bolt action into something that could easily get a 4 inch group at 100 feet. (keep in mind with the Tight bore barrel your FPS is going to jump considerably)
