I went for a day with mark Hancock a while ago and he uses a Electric Chainsaw for indoors so I bought one when I got home and haven't looked back. You get what you pay for in this market and for people that say it's not used very often so don't want a good one, firstly take a look at the chain adjuster. If it's got one of the twist action tensioners then leave it alone, they will come loose during work. You need one with a screw adjustment and locking nut, also when it's new the chain will stretch quite a bit so you will need to check it quite frequently. Most of the good ones have an Oregon chain which is quite durable. Mine is Husqvarna which I bought from my local groundworks shop, if you have one near you then go and talk to them I am sure they will be very helpful. I have no idea what your budget is but we have a company down here that repairs chainsaws, it's in the middle of nowhere and you probably wouldn't give it a second look but their knowledge is huge and the one I bought from them secondhand is still going 30 years later so you could go down this route also. I am sure you will gets lots of advice from this forum but just be aware that chainsaws are quite lethal devices, you probably don't need me to tell you that. -- Julian
