May not be the absolute cheapest price radiotech, but for support and service I would be inclined to point you at Toecutter's Den. That's where I got mine and unlike many other places, it comes fully loaded and ready to go, plus there is always someone here or there to help you through any teething problems.
Hi Rolf, have just decided to take the plunge and order an MR from Toecutter's. I see from having a look around Toecutter's that you have a BEC receiver - is that where you use the MR? I also have a BEC, the 6800CIP.
I think what they are saying is that it is possible to do physical damage to the CAM with the CAS interface and to damage the contacts of the CAS itself, nobody is going to cover the CAM or interface against self inflicted damage.
Once you change the software on any of this type of equipment, you in effect void any warrantee, but as far as I know Toecutter's will always help if possible.
PS I don't believe that there are any close ties between Astratech and the Toecutter forum, but even if both offered the same service and price, I would always go to Toecutter's, as the money goes straight towards running the forum.
Yes, I also would choose Toe's over Astratec, and if he does offer better support anyone reading this thread might now lean his way. That is if they are in the market for some new gear. I do drop into the den once in a while and see that he is well respected and trusted.
