Thanks for all the inputs so far, keep it comming.
To answer David's questions:
It will be for shop use, I had planned to buy or build a moveable table for it to move it around the garage as needed. I currently have a 10" table saw and a couple of skilsaws. I hadn't considered the blade interchangeability aspect.
Since I am just getting started my projects are not very complicated, but I wanted something that will give me room to grow so I am not shopping for another saw in 6 months or whatever. I was looking at spending around $300 or so, which would pretty much limit me to a 10". I was also looking at the craig's list option where I might be able to pick up something more robust for the same price. Locally there is a DeWalt 706, a DeWalt 708 and a Rigid 12" (dont know the model) for just under 300 that i will probably check out this weekend.
