If you use the search function on these forums, I think that you will find lots of discussions about some or all of these models and I am sure that others who have experience with them will chime in. BHphoto is a good starting point for a good selection of equipment and reasonable prices. I’ve ordered and received many things from them and was very satisfied. Also consider used from ebay bhphotoetc. to get a start for a little less out of your pocket.
