Hi. I have a McCulloch Pro Mac 610 that I bought new back in about the late 70's/early 80's. I've used it for cutting/bucking my own wood supply for most of these past 30 years. For the past 3-4 years I have had my own woodlot and now use it to fell trees also. It only has a 16 inch bar but that has always met my needs. It still runs and cuts pretty well, the oiler seems to work fine, and other than a few chains and spark plugs I really haven't had to do much to it. Honestly, in general it still does the job pretty well. I'm thinking about getting a new saw that would be similar in size, power, etc. but perhaps lighter??? (My wife even suggested looking for a lighter saw might be a good idea) And I'm curious if there are other advances in saws that new ones might offer? Or, are there things about the new saws that make them less desireable than my old 610? I've been eyeing the Stihl 290 models?? Also, bar size and chain type? But... I don't want to have too much saw for an old guy to handle! I have good Stihl/Husky dealers nearby and wonder what models in those lines might be comparable in size/power to my 610, and what experiences recommendations you good folks might be able to offer. Thanks!.
