The Stihl 025 is more of a homeowner's saw, the 026 is a commercial saw (better air filter, better rings, carb, piston, etc.). I have used a Echo 3400 (same as 3450 but top mounted rear handle) for years and find them to hold up extremely well for the price. For someone doing occasional work around a ranch, I would recommend, in order,
1) Echo 3450 (excellent value for the money, cut up to 18" wood)
2) Stihl 025 ( not one of Stihl's best, but good for occasional use on medium sized stuff, up to 24")
3) Stihl 026 ( excellent saw, will run forever, lots of power, but probably overkill for occasional use- $$$)
