I've got a couple of Mossberg 12 gauges. One is a 835 and the other is a 500 Turkey Thug. I like the pattern of the original chokes, but I'm looking for one better. Any suggestions?

I can't afford to spend too much for a choke either. So about $50 is my max (that's also why I can't afford to try many of them out).

Thank you.
