I have had all the brands over several years, then last year a hurricane rolled through our area and dropped 30 trees on my uncles property. He was quoted $8-$12,000 to clean it up. I offered to do the work if he bought me a good professional chain saw ($600 - for the model I chose). What your looking for will be ALOT less in price.
I went with a Stihl MS 360 Pro. Now, I know you don't need that big of a saw for your uses, but I highly reccommed the Stihl brand. After countless hours of using this saw, it is dream to use. They make many models and several of the models can use 2-3 different bar lenghts, so you can get a 12, 14 or 16 inch bar and chain as your needs grow and switch between them.
As far as starting - I let the saw set for 13 months (with Stabil in the fuel) inside my unheated outdoor shed and pulled it out the other day, to assist a neighbor in dropping a huge silver maple, it started in 2 pulls and ran just like I used it every day.
Also, most smaller chain saws (other brands) use a smaller chain than 3/8, you got good advise when they told you to look for a saw with a 3/8 chain. The Stihl saws all use a 3/8 inch chain.
After using a Stihl saw - I will NEVER buy any other brand, the difference is like night and day. Go to a Stihl dealer/repair shop and they will have a saw that you can demo right on the premisses, and you can get a feel for it.
Hope this helps.

P. S. for your needs look at the following Stihl models: MS 170, MS 180C Easy2Start, MS 210C. They all can use a 12, 14 or 16 inch bar, and can be switched out in minutes.
