I'll be discusing my fan film in another part of forum but I need to look like a ghostbuster and I plan on making all my own props for this so I need the following plans-

The Proton Pack
The Ghost Trap
The suit
Thanks to anyone who can help.

You should take a look at your one stop shop for props, GB Props.com.

There are also many other good sites to check out, ASAP, GB Parts Page, East Props.. and some others, check the links pages.
