Ditto on the La Sportivas -- rarely cold enough in VT to warrant Koflachs. Better for hiking, ice climbing, snowshoeing, etc. Only time they might fall short is in the dead of winter in the Whites on multiple day trips.
Get some sort of insulated single boot like the Nepal Evo. Those fit a lot of people well, so start there. But, fit trumps all, so go to a proper climbing store (there are plenty in VT/NH) and try them on with a good bootfitter.
Scarpa, Kayland, Mammut, and others make good boots. LaSportiva has a huge lineup with lots of choices, as do most of the aforementioned makes.
Look for a rigid or nearly-rigid sole with welts front and rear for attaching crampons. Then try them all on until you can lace them comfortably and hike without your heel sliding up and down. That's common with poor-fitting climbing boots, and will blister like mad.
