IMHO, regulators are over rated. There is no need for them other than for whiz-bang coolness factor. Do you really want another failure point?
Know your gun. Refill when you need. Shoot'em good.
What? To each is there own......
Peep, If you want accuracy and more shots per fill (if tuned down) a regulator is a wise choice. Watch some youtube videos and I'm sure lots of folks here will recommend a higher end gun, it's worth it to save a little longer
Don't have to worry about saving money, this is a relatively inexpensive hobby. Just like to fool around with guns I can walk away from. Have to go with Odoyle on this one.
