Good quality chainsaws cost some money. You might want to take a look in the classifieds here see what might be available. A lot of guys here rebuild saws and sell them and they are deals compared to new. Or alternately post a "wanted to buy small saw" ad yourself. I'd stick to newer saws with good anti vibe and chainbrakes for your situation.
I have a small "homeowner" class husky, the smallest/cheapest they made at the time, I bought new several years ago for just at two hundred and it has been just tops for reliability, easy starting and cutting. I've used it a *lot* even on bigger stuff where a much bigger saw would have been better. I mean, this is a work saw, I have run it much harder than harry homeowner would.
FWIW, echo makes nice saws as well. They just need to be initially tuned at an echo dealer before running..well..same as any new saw needs that today. The EPA has made it so hard for the saw manufacturers they ship new saws wayyy too lean in order to pass emissions.
And if all possible, try to find non ethanol gas for your saw gas mix, use synthetic mix oil, or if you aren't cutting a whole lot, a lot of stores carry the pre mixed fuel in a can for around five a quart. I know wally world and home despot have that. I picked some up to try it, trufuel, and like it. Ya, expensive, but the stuff works good and you won't develop the issues that ethanol causes in small engines today. Ethanol fuel is just rank stuff, eats fuel lines and carbs, etc, separates easy, attracts water into the mix. Avoid it for your saw and other small engine stuff. Canned fuel lasts two years, ethanol fuel two weeks. It just gunks stuff up bad if it isn't used all up fast.
