There is a nice gamo maxim springer in the sales section for £240 with 3x10shot mags. Get a cheap scope and you have a tidy set up. Poisoning i found crap on rats as if the food source is more tasty they will bypass the poisoning boxes. You will need a dimmer light/torch if night shooting them as they are very wary. Be careful handling the buggers i used a pair of barbacue tongs. Burn the bodies is the best thing to. Take a look at that gammo ok. Chris
