By "fancy" I'm guessing that he meant expensive, aftermarket. There are some choke tubes that can cost upwards of $70, that perform no better than some factory chokes. The opposite is also true.

Phil Bourjaily touched on the topic of choke tubes not too long ago on the show Gun Nuts. His main point was that modern production choke tubes perform much better than those from years ago, making after market tubes unecessary. I have to disagree, but only becasue I've invested more than a few $$ on expensive turkey chokes (so there!)

My advice is to check the pattern of your gun with the loads you intend to shoot before investing in an aftermarket tube.

But...do check if choke tubes you have are rated for steel shot. I recently purchased a Benelli SBE II. The choke tubes suitable for steel shot are clearly marked as such.
