Living in those northern usa states, such as CT, MAine, new hampshire and what not, in my opinion only real winter tire is studded tire. I can not recommend website, and not sure what is available in usa and the pricing, but if you gonna buy studded, make sure its at least mid range quality, and make sure its factory studded and not dealership studded. If somebody throws you an old myth that studded tires perform worse than non studded on dry or wet tarmac... its bs, its an old myth. In 2015 Norwegian winter tire test of 20 tires (10 studded and 10 non studded), in breaking, accelerating on wet-dry tarmac out of top 10 best performers, 7-8 were studded tires. If you live in more mountainous area, have some hills to climb, etc.. when the melt down comes, and have that almost pure ice with water on top, you will be stuck with studd-less tires. Also at the start of winters, mother nature loves to joke around and drop freezing rain. Only negative aspect is noise. I just had goodyear ultragrip ice arctic (factory studded) installed, and drove in ~11inch of heavy snow with no problems. These are considered as top 3-5 studded tires in the world, on the par with hakapellitas 8 etc. paid 300 euros for R15.

8.8 point Nokian Hakkapeliitta 8 8.6 point Continental IceContact2 8.6 point Hankook Winter I * Pike RS 8.5 point Goodyear Ultra Grip Ice Arctic 8.5 point Pirelli Ice Zero 8.4 point Dunlop Ice Touch

Out of these if you on a tighter budget, hankook and dunlop should be the cheapest. In Europe these considered as upper range tires, but they perform on elite level. The go for 50-60 euro per tire, vs those elite tires such as nokian and what not going for 70-90 euro per tire. First two places has ~190 studs per tire, hankook 170. other ones around 100-140.
