you need to search and learn. go to bagginit.com, read everything there, and then come back here when you know what you are getting in to.
you need to decide on what size bags you want, what size and number of valvex, link system, where to mount your tank and compressor, what type of compressor and size tank, the list goes on and on. search around on this forum and read on bagginit.com
i wasn't trying to be mean in that first post man. its just that there are SO many options and we don't know exactly what you are looking to get out of your setup. so its best to read as much as you can, and then we can help you out if you don't understand something.
read up dude. i've read just about everything there is to read, and i'm not even bagged yet.
