Do yourself a favor. See if you you can find a used Stihl that needs repaired and take it to that dealer and see what they say. If they offer to fix it, buy a new saw from them. If they try to sell you a new saw, walk out and never go back. They may be a great shop, or they may be lousy. Find out before you decide to let them be a major factor in your decision.
Between the 362 and the 261, start with the 261 and decide if you need more. If so, add a 60cc saw. If the 10lb, 50 cc, 4.0 hp 261 is enough for your needs, keep the rest of your money
