I guess how much you want to spend. You can get an Echo CS-310 at Home Depot for $ 200.00. It's a nice 14" saw. Or get the electric for $ 100.00. With the gas saw you need to be sure to put stabilizer in the gas and drain and run it out of gas before storage or you run the risk of it not starting in a year. I prefer a gas saw over electric , but that's me.
I will agree with Ken.An Echo should fit the bill/ However I would recommend that you use premix fuel in it.Yes it is expensive however you should not have any issues related to gas, ethanol, ext.
I'm in the middle of these two posters. The pre-mixed gas is probably the best, and if you are only going to be running for a fill maybe 2, go for it. However, it is ridiculous on the wallet. You will be just fine if you buy RECREATION gas (rec gas). It isn't available everywhere & it is more expensive, but it doesn't contain ethanol. It is intended for boats, but it should be advertised just as much for small engine equipment.
If you want to use regular gas (though not rec), you need to get a product like Startron to neutralize the ethanol. It also does the same thing as Stabil, in terms making the storage time of gas longer. Plain Stabil really is only good if you want to store gas for you truck, or something that is better suited to handle the ethanol that is still there.
For what you are talking about though, I'd get a battery one. Even if you get great gas, there is still other maintenance. I wouldn't trade my Milwaukee for another saw. It has handled everything I've thrown at it just fine. My only gripe is lack of a case for it, but it's not gas so I don't care about keeping it in my truck all the time un-cased.
I saw an uneducated homeowner buy a gas string trimmer the other day, and I know he will regret that purchase either next year, or for sure the year after. He will love the power now (over kill for most people as it is) and hate the upkeep in the following years after storage. I think many people feel that way about chainsaws. The less you use some tools, the worse off they are.
I will admit, if it's your only tool on a specific battery platform, the upfront cost is more, and loses some of the attraction.
