Looks like they have the saw picked out, I would suggest this:

But it is way out of your price range. So forget that!!!
Make sure you buy saw chaps:

Here is why you want these safety items:
Every time you think about starting that saw, put these items on. I may come across as harsh but I am looking out for you safety like somebody looked out for mine when I was STUPID!!! Still may be... But that is another topic.
Second, there are lots of excellent resources on the internet. Google the BC faller training standard and US forestry service manual. They are both free and a great place to start. Stihl and Husqvarna both have videos on youtube. Be safe, it is a lot cheaper than getting fitted for a new head. That isn't a joke. People are killed an injured every day by these things we call chainsaws.
