Do Any Of You Guys Know Airguns?

I've been shopping a pellet gun for a few weeks, I've got to eradicate the critters that eat my garden.
I live in a development, but our back yard is a common area and golf course. Our back yard slopes down from the house, so it's safe shooting. It's a long ways to the next house, too.
Regardless, it's gotta be quiet. The quieter the better. SCUDS and remotely operated .50 cal turrets are out. The neighbors would b1tch before I even lit them up.

I've been looking at the Gamo Whisper Fusion.
Thing is, pellet guns are a pain in the ass. .177 caliber are faster, .22 caliber hits harder. A .22 would be fine with the range I'm looking at and it'd be a better choice, I'm leaning that way.
The scope on that Gamo is considered crap.
From what I understand, it's best to piece a rifle together for your needs. Gun, scope, scope mounts, and accessories.

I was hoping some of you guys might head me in the right direction. I'd far rather take your word for it than a salesman at pyramid or airgun depot.
It really does look like it's in my best interest to piece a gun together than pull one out of a box, so I think that's the way I'd like to go.

Any input would help, even if it doesn't go directly to selecting parts and pieces. Except "put up a scarecrow" or "take pity on the garden eaters". I tried to talk sense to these ignorant bastages and even suggested a treaty. They patently ignored me. Diplomatic relations have been severed and war is imminent.
