Looking to upgrade to an SCBA 4500 psi tank. What are people using? I have found the topgun-airguns guy that supply the tiger shark and great white, is this what people are using the most? I have an anschutz 2002 so getting one of their tanks the the option 2A would allow for filling of the 2002 cylinder?

Thanks!

Yes, Joe Brancato (AirTanksForSale.com) has the best stuff available

I have the Tiger Shark with all the extras and it's a sweet setup. I picked it up second-hand for a good price, otherwise I would have bought the Great White. When my tank ages out I will get a replacement 97 cu/ft bottle and the rest of the current hardware will switch over. Buy the biggest bottle you can afford.

Joe was very responsive and helpful when I made a phone call to him when all the glycerine leaked out of the main gauge.

There are some other options out there (airhog.com, etc.) but the ATFS.com products are just a bit nicer.
