I normally don't use a landing net, unless I'm in a boat, and have hooked a large fish that I don't want to risk trying to "swing" into the boat.
But, I've had a few large fish break my line at the shore lately, because there wasn't a good place to land them, or I couldn't reach them quickly enough. I'm also planning to get a kayak soon, and think a small landing net would be good to have there as well.

The net doesn't have to be really big, but big enough to at least hold the front 1/2 (or more) of a decent-sized carp or catfish.
I want one small enough that it won't be a troublesome burden to carry with me during "Lunch Outings".
I also prefer the rubber-mesh nets, since hooks don't tangle as easily in these, and I may on occasion use spinning gear/lures when fishing from the kayak.

Cheap is good...I'm not looking to spend $40+ for a net.

I see Bass Pro Shops has some nets in the $10-$20 range...has anybody reviewed those nets? Other suggestions?
