Any concerns with buying GRT Efis?

[stevek7m]

I am needing another Efis for a new airplane I’m building, I have a GRT Efis in another airplane that I like just fine! My biggest concern is that with Garmin and Dynon that Grt may not be around forever, what do you other guys think?
Thx, Steve

I sure like my GRT EFIS and will put one in my next build. The best value as far as I can tell and don't see or know of any reason they won't be around as long as the next guy.
