CopterX sure looks nice, thanks for the vote of confidence.
My interest currently lies with what appears to be the brand new "Tarot" clone:
US$106.27 Tarot 450SE V2 GF Kit (airframe only)
US$206.02 Tarot 450SE V2 GF Kit (with bat, esc, motor, servos)
Those are stunningly low prices - and it claims to be 100% part-compatible with Align.
