Questions 1 -3 are state-specific and should be asked in the Michigan State sub-forum.
Question 4: Have you handled and fired any of those? You have to get whatever feels best to you. Everyone has their preferences and favorites. Go rent and/or borrow a few, get educated in their function and design, and fire them. Then you'll be able to decide for yourself what you like best for you.
