Wait.. wait.. I have a left handed hammer.. does that count?
My experiences with Tower are 100% favorable. They are easy to deal with and will help out when necessary. I ordered five Airtronics servos for a plane a while back. They sent four of one type and one of another. When I got them, I noticed the discrepancy and called them. They told me that they would send the right one (umm.. the correct one..

.. that's for Minnflyer) and to just keep the odd one. Nice people to work with, for sure.
