Forget milling your own wood, IMHO, unless you just absolutely can't let it go.
Let me tell you of a mistake my parents made when building their house...they used the wood off the property, sent it to a local sawmill, and made the mistake of not drying it long enough. This has caused problems. So, unless you are willing to wait a while for the wood to dry, it's going to give you issues of dimensional changes. And that's bad for precision stuff like houses, furniture, etc.
We use a couple of older Poulans, and we mainly cut with bows. We do have one 20" straight bar on one of the Poulans for felling trees. We use Oregon chains. Dad and I are looking at buying a Husky if we can find a bow blade to fit it.
