I never closed the loop on this thread.....I ended up going with Echo SRM-266, but from Home Depot. After comparing to Echo models at dealers, the HD models are exact same ones at exact same price. BUT Home Depot gave 10% military discount. AND, from the dealer, once I bought it, it was mine. They'd fix it if broke, but otherwise stuck with it. Too heavy, not strong enough, hard to start, just don't like it? Too bad if bought from dealer. But from Home Depot, just return it. Also got an Echo CS-490 20" chainsaw at same time.
Both have been great! I use the .105 Echo diamond line and it cuts great and holds up well edging along concrete. The speed feed head refills super easy. Both start real easy if follow instructions & close choke as soon as a hint of sputter. But never more than a few pulls & either fires right up. The only complaint maybe is the chainsaw. at 50cc & 20" chain it can get bogged down at times I think it shouldn't. Maybe should have got the 60cc or I just am not a great operator, but it does really well even if I can sort of bog it down on something real fat.
I'm sure Stihl is great too, but after using for some time now, am very happy with the Echo stuff I got. However, i can't think of a good reason to get from dealer vs HD in that case. Dealers inflexible on price & were all the same - just said wait until a sale but otherwise pay full price. Not that huge a deal, but both together was almost $700 so 10% was nice - like getting string, spare chain, 2 stroke oil, for free and still money left over. But really, not entirely sure if I'd really like both so the option to return if they didn't meet my needs was huge. Also decided not going back to Kubota dealer who had the Echo & Shindawa since he flat out lied that their models of Echo were somehow better quality than what's at HD - all are exact same model numbers, exact same specs.
