X2 on Hutchins da's and straighlines. Also have an old craftsman thats 25 + old, and one of the hf ones I bought while working at someone else's shop. The taller handle style like the IR posted are generally more aggresive sanders, and the palm style a little smoother action for finish work. The grey $40 hf one has worked fine for me , it's 4-5 years old and I dont have to worry about it sprouting legs. A better pad will make a difference on any of them.
