Went to my dealer the other day to buy another trimmer. I've been a little disgusted with the Stihls so I thought I would try a SR260 Echo. I thought $299.00 was a good price too. Other than trying to get used to the new head vs. the Stihl.........I love it! Plenty of power, no bogging, cranks in 2-3 pulls vs 10-15........very happy. I wonder if you can put a Stihl head on an Echo trimmer? If you can and have done it let me know. Then I would have the ultimate trimmer. Now......the rest of the story. While I was there we decided it was also time to get another blower......the BR 400 probably won't make it through another season without going down for repairs.........she's been a good one. My choice was to get the Echo or new Magnum BR420. I thought to myself and said "self, the old BR400 has been a good one, surely the 420 will blow the 400 away.........let's get the new Stihl". Self agreed whole heartedly. Let me say that self and I have done battle over this one. My BR400 has more guts than this new one does and I'm bout tempted to take it back and trade it for the Echo. I got it for $399.00 and have used it for maybe 1 hr..............long enough to know that the MAGNUM ain't got no guts..........it's just purty cause it's new! I was really hoping to step up a little in power but instead have fallen back. I guess after using the Shindiawa EB630 last year (borrowed while mine was in shop) nothing else is going to compare. Would I be making a mistake to go to the Echo PB650, is it any stronger than the BR420? Self screwed me on this one Echo might be all I put on my trailer before long.
