They have been almost impossible to get for quite a while. My EVO12/synth was on order at NorthEast Sailplane for about 3 months before it showed up about a month ago.
HOWEVER, they ARE more available, sort of, now. But you have to be patient and do a lot of calling around to see who might have what you want in stock. I think Tower is showing the crystal models in stock at the moment, but again, you'll have your best luck if you check with ALL the places that have been known to carry them. I think even Karlton (Smashed Toad also at RCgroups.com) got a few recently but I don't know if he's sold them by now or what.

A question for those that have the Royal Evo 12, where did you get it? It's been a few weeks since I last checked, but when I did, everyplace I called said they did not have any and were not sure when they were coming in. My taxes should be back in a few days and I'm looking for something to spend it on
