CurlyDave -
You sound like someone who has taken the time to think out their approach to their land and what they want to accomplish on it. That's an important step that many folks overlook. I'm sorry you suffered an attack here on this board, especially since it seems someone was jumping to unfounded conclusions. From your posts, you strike me as someone who is concerned with your land and with "doing it right". Good luck to you and don't forget to take the time to enjoy the process.
On the chainsaw issue: Here in Vermont, most of the people I've seen who spend much time in the woods with a chainsaw seem to settle on one of the following brands: Husqvarna, Jonsered, or Stihl. There are probably other good ones, but that's what seems to hold up well for folks around here. Each of them make a variety of levels of saws in any one size range. I'd advise taking a step up from the entry-level, homeowner end of the range. They are still good saws (I don't think any of these three make junk), but the higher end ones have some better features (including better vibration damping) and tend to be more durable and more repairable.
I think you are on the right track with a 16" bar. Longer bars are more fatiguing, and can be awkward in tight spaces or when limbing. As someone else noted, you can still get down more tree than you are apt to want to handle with a 16" bar. I would also recommend some thought on engine size. 50cc engines are a good match for a 16" bar, especially when paired with a .320" pitch chain. You can go smaller in engine and save a few ounces, but in my experience the ounce saved in this particualr size range don't make up enough for the power lost.
If you don't mind my drifting into another topic: There are much safer ways of dropping a tree than pulling it over with your tractor. Not to say you should never do that, but that should be one of the last tools you reach for, not the first thing you try. It's really worth getting some good training in chainsaw use and maintenance. Helpful tips from a friend can be nice, but an organized training workshop is well worth the effort. One of the better ones I've seen is Soren Erikson's
Game of Logging I've been through 3 of their four levels of chainsaw training and found each of them highly worthwhile. They cover precision directional felling, safety (in use of the chainsaw and in planning your cut), basic maintenance, and dropping "difficult" trees with back or side lean, amoung other topics.
I had little experience with a chainsaw. I sought out advice from experienced friends (even one who was a logger). I finally decided that I knew just enough to kill or maim someone (probably myself), and that I wanted to be around to see my kids grow up, and have use of all my limbs while I did so. As you can probably tell, the training made quite an impact on me.
I didn't see much on their website about organizations offering the training out in your neck of the woods, but it migh tbe worth touching base with them to check. At the very least, they might be able to recommend a similar organization in your area. I also know that some of their trainers have traveled to other states on occasion to offer training.
