@coreyt I also have a Gyrodec SE and enjoy it very much. My current tonearm is a SME M2 9R that i purchased from www.smetonearms.com. This might be an option for you as you already have a SME armboard. Alfred was a pleasure to work with, if wish, he'll also rewire the tonearm and upgrade bearings.
I've still got my original TecnoArm on the shelf, I should probably do something with that.
