The thumb holes are nice, a bit of areach for my short fingers though.
As for the dies...
If I remember correctly, the dlx kit is a seater, full length, and neck die. That is all the dies you NEED. If you are getting into paper much I recommend lee's factory crimp die; also good for rough handled hunting loads. But it isn't needed. You will need a trimmer, stick with Lee's; cheap & easy.
