You sure as hell don't need a pro saw for the little bit of light use you've described. I cut about 15 face cords of firewood every year and my Stihl MS290 Farm Boss is still going strong after 7 years of that. It's only a "firewood" rated saw by the manufacturer and would be more saw than you really need. Hell, it's more saw than I really need most of the time so I bought a smaller, lighter Husqvarna 445 3 years ago. I've used that one for the bulk of my firewood ever since and it's still running/cutting like a demon. It would more than serve your purpose and only cost about 300.00.
