RE: How do I start.
Good to hear from you Dave.
I'm surprised to hear about your problems with SIG. I've always found their service to be excellent - better than most. Email can be quite unreliable, due to spam blockers, but a phone call usually gets the job done. I know how it feels though. I've spent months waiting for items to come in at the LHS, or by mail order, sometimes never to receive them. Very frustrating.
