my 60s are an X-Cell Pro Graphite, a Raptor and a Baron XII, the 50s are another Raptor and a GPH346, in the 30s I've got yet another Raptor and a Nexus (in fuse). i like the Raptors and have no complaints out of any of the 3, the X-Cell (pictured below) is by far my favorite but they do come with a hefty price tag attached (well worth it after you learn to fly though). I've never liked the century heli's myself but i do know allot of people who like the way the fly. and the last link you posted are gassers not glow.
