I've been happy with my Dual GPS150 as well. At the time I chose the Dual because I was sure I would break off the BadElf one that plugs directly in to the ipad. Now that BadElf has the Pro model, I'm sure either would do a fine job. I wanted ADS-B and AHRS (iLevil) but decided to wait a few years for coverage to be better in Idaho and prices to come down.

FWIW, here's the most current ADS-B coverage map, courtesy Sporty's: http://www.sportys.com/source/images/st ... 2013181931. However, it's a little misleading. When I flew to OSH in July, I flew to Luverne, MN, just east of Sioux Falls, SD, on the first leg. That traverses what appears to be a significant gap across western Nebraska, yet I had continuous coverage from shortly after I left the pattern at Greeley all the way to Luverne. I flew at 7500' most of that leg. I have gone up to Laramie several times since buying the Mini and Stratus II, and whether I have continuous coverage depends on the altitude I fly. If I stay relatively low, like 8500', I'll lose it as I cross over the ridge north of the CO/WY border, but if I fly at 10,500', I'll have continuous coverage all the way until I descend into Laramie.

Since traffic only works if there's an ADS-B out aircraft broadcasting, that's not a very useful feature yet, but it's interesting how many non-airline ADS-B out-equipped aircraft there are (their tail numbers show on the screen). But the weather part is extraordinarily useful.

A larger screen than the Mini has would be nice, but it would block so much in my airplane that it wouldn't be as useful--and for me, it would not be a good alternative to strap it on my knee. I've found using the Mini on the yoke comes close to a perfect compromise, as I've learned to easily expand and contract the screen as necessary, even in turbulence.

I've got the Garmin Glo, and pretty sure its cheaper than the Bad Elf. Works well but needs USB to charge. Doesn't like sitting on the dash in the heat (as per any electronic device) so I just pop it in the glovebox when not in use then put it back on top of dashboard with a bit of Velcro when needed. Updates a lot faster than standard iPad inbuilt GPS.
