In regards to a Zaon, which one to the majority of you own? An XRX or and MRX? Im trying to toss up the difference so I can decide which one to purchase. Is it really worth paying almost 3 times the price for an XRX? Or is an MRX sufficient in supporting a good lookout?

I have the cheaper unit and am very happy with it. I would like Flarm as well, but I am sitting on the fence until I have tried the new combined units. One of the issues is that you will be mixing GPS altitude with encoder altitude, which may confuse the otherwise accurate vertical separation which is the big benefit of the devices.

I have the smaller Zaon MRX, having tried Rod's first and been impressed. I don't have room for the larger unit. I also have Flarm, and lent it to Rod for him to try, before he wrote his article. We both concluded it's good to have both, if one can find room, or with more recent technology combine both in one unit.
By the way, as far as I know, Flarm uses a pressure capsule for height, not GPS altitude. More recent Flarm units have the capability of acting as GPS logs as well is the alert functions. For logging purposes, in gliders, the pressure capsule has to be validated periodically. I had mine done earlier this year.

I purchased the MRX purely as a cost issue.
I think if I was lookling in the price range of XRX I would go for the new PowerFlarm.
The MRX does its job, yes it does not give direction but you can quickly figure out if something is a threat or not by the distance shown, getting closer or not.
To be honest sometimes I think it causes stress, showing traffic you cannot see and without the MRX you would think you were all alone.
Not sure if thats a good thing or not.

they actually seem to prefer to MRX over the XRX. Obviously if you want to hook it up to your GPS the XRX is the one to go for as the MRX does not offer this feature. I also find there is no need for the headset adaptor as you can hear it anyway and see it on top of the glareshield.

I spoke to the PowerFLARM people at EDNY recently and tried to impress on them that if they could deliver a box which offered azimuth data on Mode C targets, they would have a fantastic product. It is obvious that it can be done. But they didn't seem interested.
