If I were in the market for a new one, I would take a look at the Tikka brand, I believe Beretta is the importer. Easy to search up reviews and tests. Their T3 model is available in a left hand setup.
I believe you're in great shape with that chambering, it seems to be an easy cartridge to get to shoot well. Make sure you stick a decent modern scope on whatever you settle on, modestly priced ones seem strides better than higher end stuff from just ten or fifteen years ago.
My favorite part of shooting my .222, a plain jane varmint rifle, is that I can generally keep the scope on the target at the shot. The fun factor goes up when you can watch what's going on. Also, consider a predator call, they're a fraction of what they sold for not too many years ago. Without breaking a sweat, you'll blow through that thousand rounds. Have fun.
