I'm looking to replace the Ameri-King AK450 I foolishly purchased. On the recommendation of a fellow TeamKitfox member, I've settled on the Artex ELT 345. A problem with it is the size of the panel mount switch. I found, on Aircraft Spruce, a Slim kit that has a switch that will fit the hole in my panel the Ameri-King switch required. The difference between the Slim kit and the package that has the original Artex switch is about $200 more for the slim kit. Does anyone know why there is such a big price difference between these two packages? Is it just the switch or is there something else? Seems a little pricey for a different switch.

Thanks,
Fred
