AC R/R/R equipment for DIY

[Jeeper]

How many of DIYers have their own AC recovery, recycle, recharge equipment? What do you have and why?

I am looking for an affordable R/R/R system but don't want to spend a lot so looking used. Curious to see what others have.

a large shrader valve tool, one of those $12 hoses, a gauge, and a can. or i use the hose with the built in gauge...
just an old snappy r-12 machine, we have a robinair at the new job, i've seen them come up on CL once and a while. done the can and hose thing alot at home though.
