Hi Tom...
Yes I agree although both are very good sounding arrangers of which I have gigged with both, but IMO better for home use at that weight. ......they are just too big, heavy and bulky for daily In & Out GIG duty.....I use the S910 now and couldn't be happier, but I still want lighter & smaller. Harmony M is also a good little unit. Good luck
