I will 2nd the opinion of RogWabbit. A 60 size 3d aerobat will need at least a 90 or bigger in my opinion to excersize its 3D potential
60-80" span is a very wide spectrum and covers alot of different styles that are available. I have been wathicng the progress of ExtremeFlightRC and there has ben poistive feedback on their current lineup.

The UCANDO 60 is a good choice as well if you want something right now and dont want to wait.
good luck
