For what your wanting to do and with your level of expierence I would find a clean 028 Woodboss Stihl, they are an older model Stihl, but built like a tank, virtually bulletproof if fed with good fuel and mix and a little maint. They will run circles around a 250 or 025 and can be bought for 150-250.00.
+3 If you are dropping down from the 36" tree requirment, an 028 is an excellent choise. My dad bought the Electronic AV version back in the early 90s. It had a crap carb on it from the factory, but it still ran well. Just took 4 or 5 pulls to start it. We finally found a good Stihl shop, and the guy threw a new carb on it in 2008 for $20, and now it fires on the second pull. Very great fire wood saw. Dad has used it to maintain the 250 acre farm that we hunt on for the past 20 years with no problem. They had a 48" maple in the back yard that they had taken down 2 years ago. Dad used that 028 to buck the whole thing into 14" pieces. He would noodle, then buck. It took him several evenings to get the trunk done, and the stump cut flush to the ground, but he did get it done. I didn't have the 064 at the time. Would have made the job a lot easier, but that 028 is enough saw to do anything that you have any buisness doing. It's a good ol saw.
