A Syma 2ch was my first RC heli and I have loads of fun with it. It had nice forward movement and was like a giant Airhog Havoc. I soon bought a 4ch single rotor heli and I have yet get any single rotor to land safely I then bought a coaxial and it is my favorite helicopter (Colco Apache 4ch). My collection now includes four miniatures (Havoc like), four 2ch Symas, a 2ch Apache Coaxial, a Colco 4ch Apache coaxial, A Walkera DF #4, a Blade CP, a Blade CX and a couple "Scale" heli's in the making. More on the way!
Of them all the Colco 4ch Apache is my favorite and the easiest to fly. The miniatures are real fun too because you only have to chase these 2ch critters across the room instead of across the park like the big 2ch ones.

However, my collection justified my wife to start collecting also... we now have eight ferrets! The don't fly to well but you should see the arobatics they can do in ground effect
