A tidy piece of kit with everything that you need for the upgrade and at half the price. If you don't mind waiting a bit longer for the postage......50% cheaper than buying it in England... well worth it. Well done guy's. Andy Hornby

Customer service was great. They responded in a timely fashion. But it took so long to ship, that I ordered from another company and received that one, before I received the one from sigma. The guy was cool about it and told me to return it, but it's just a lot of work and I elected to just keep it. So I have no idea if the parts are good or not.

Sorry, but again we do not work weekends. Customer purchased Friday night, April 12, we shipped Monday morning, April 15th. We believe that for at least 2 days a week people should rest/relax, and spend time with family / friends. Apparently in today's world, that does hurt a business. Sorry, but as a company we are not going to sacrifice peoples mental health for the all mighty dollar.
