I have the Echo SRM-230 and love it. I am a homeowner and care for two 1/2 acre yards. The current Echo replaced an Echo SRM-2400 that lasted over 20 years. A commercial quality two stroke is simpler than a four stroke with fewer parts and will last you many years with proper care and maintenance. A cheap trimmer can drive you crazy with problems. As mentioned above don't go to a big box. I purchased my Echo from a large dealer. It was started prior to leaving the store and came with a tank of premix. It was even $10 cheaper than at a local big box.
