Well, I have the following:
The P4 (of course)
Hubsan H502S (GPS, altitude hold, position hold [via GPS], FPV 720p camera)
Hubsan H107D+ (similar in size to the Eachine H8, but with altitude hold and FPV camera)
Parrot Mambo
Eachine E10WD
Cheerson CX-37 (FPV micro hexacopter -- really cool little flyers, another $30-40 way to play)
Of these, my favorites and the ones that get flown the most are the H502S, E10WD, and the CX-37. The latter two indoors with some outdoor flying when conditions are calm, and the 502 outdoors for full-on, major out-of-LOS flying where you don't want to commit Hare Kare if disaster strikes (hey, $150 ain't chump change by any measure, but it is a fraction of the hit you take if you lose your P4).
I unbelievably took the 502 out over 1000m distance at 130m elevation yesterday, before I lost contact with it (it has RTH). That's my new record -- I made it 800m previously. This is stock.
I'll plug the E10WD one more time for the indoor flyer. Watch that review video. The FPV option, when you want to play with it that way, is a really great thing to have.
And for grins, here's some lazy Sunday morning harassment of Duke and Buddy with the CX-37:
