WFUJIM, I personally would never buy a ski without demo'ing it. I have been tempted more than once by great reviews from trustworthy sources and a great deal, and very nearly pulled the trigger. But in almost every instance, when I finally got to demo the ski, I was glad I didn't own it. Most were unremarkable to me, and some I hated. The feeling that each individual wants from a ski (and how each ski responds to each individual's size and technique) is just too personal.
Although free demo days are a rarity, I know some of the areas you mentioned skiing in NE have shops at the mountain base where you can demo as many skis as you want for a fixed daily charge (usually around $50) which they will deduct from the ski price if you buy. Stratton, for example has two shops in the base village, a short walk to the lifts, that offer a variety of models (Volkl, Blizzard, Kastle, Rossi, Salomon, Dynastar, Nordica, K2). Of course if you have targeted a manufacturer they don't carry, you're out of luck. For example, I really wanted to get on some Fischer Progressors and Head Supershapes but couldn't track down a convenient place to demo.
Price-wise, most shops in NE are selling most of their remaining ski inventory at 50% off retail. You can probably find a 10-20% better deal shopping on-line, but I ended up buying where I demo'ed because they were very helpful, offered great service, and came pretty close to the best on-line prices when I factored in my demo charge allowance (money well spent).
I'm sure you will get no shortage of recommendations about skis that you should consider, but my $0.02 (I'm about your size, but a lot older), for what you described: Dynastar Contact 4 X 4, Atomic Nomad Blackeye, Volkl AC30 (all of which I have skied). On this list of skis I didn't get to try that sounded like they would be a good Eastern choice: Fischer Progressor 9, Head Supershape Speed or Magnum.
