I have a Chrony F1 and it works for me. You can spend more money for more bells and whistles if you want, but I doubt that they are that much better, long term.
I've shot my chrony rods four times. The first time I had the aluminum factory rods. Then I switched to wooden dowels. None of the four bullet hits damaged the unit.
I load, 9mm Luger, 38 and 40 S&W, 38 Special, 357Magnum, 45ACP, 45 Colt, 223, 300 AAC, 243 and 30-06
