Presumed,
I wouldn't say that 825fps is low powered, plenty good for most air rifle tasks. As you mentioned power wise, you would not believe my PH6, it is a canon. When I bought it I had no idea. I had to change my normal metal and plywood backstop, now I have an old kevlar vest that I use that is holding up well.

Now let me tempt away. Filling a rifle from o to 250 bar with a manual pump is a little daunting, but after the first fill, topping off isn't so bad, I never let pressure get below about 90 bar, or try not to. It isn't as easy as cocking a barrel or lever though. As far as condensation, I live in AZ so don't really have that problem, if I move to the east coast I will buy an inline filter which I have been told takes care of the problem. I think for field, hunting, or pest control the PCPs are the way to go, even with the issues we talked about. You obviously love air rifles, I would say to definitely give a pcp a try. www.airgunsofarizona.com usually has a decent selection of used guns, if price is an object, I think for your purposes the Air Arms S200 might be perfect. Another good site is www.straightshooters.com. Chris
