I have the Echo SRM-260 trimmer and -280 edger. Both have plenty of power for their tasks. If I were doing it again, I would go split-shaft so I could run attachments and only have one power head to feed and maintain.
I would want more power than either offer for blade duty, so I am ambivalent on solid versus flex shaft for trimmerduty.
