Adjustable Tank

[SI|ENT|3O|3]

I have a 48/3000 PMI tank and i have a retro valve. i love the retro valve but would like my trigger to be a little more reactive. i know that a adjustable tank would do this, but i don't have a lot of money. So my question is, what is the best deal on an adjustable tank????

i know i should make a seperate post for asking if anyone has a used one they would trade for my tank plus like 50 dollars. thanks a ton everybody.

You might be able to find a used 68/3000 flatline. They go for around 180-200. Look in the classifieds here on AO. That would probably be the best compromise.
