Currently in production (other than Savage/Lakefield) are Anschutz, Ultra Light Arms, and Cooper Arms. Out of production are Dakota Arms, Kimber, and Remington. Pricing: Anschutz ($550+), Ultra Light Arms ($800+), Cooper ($1250 - $4000+), Remington ($200), Dakota ($1800+) and the Kimber ($800+). A few custom action makers catering to the rimfire benchrest crowd make LH actions, but they're very specialized and a complete rifle will run at least $2000. A high quality rimfire is a joy to own. I shoot mine more than any other gun I own, so it earns it's space.
