I work with in the tree business so working with chainsaws everyday, so I chip in my advice.
If you do decide on a chainsaw no matter what brand it is its all about the service and which is the closest service center, for me Stihl is only 5 minutes drive from me the Husquvarna is a 20 minute drive from me so I picked Stihl just in case I ever need a spare part etc.
Secondly judging by the size of your property it really doesn't look like you need a big saw something in the 35-40cc range is plenty look at the Husquvarna 135 its not a pro saw but its got plenty of grunt in it.
Ok I have to be a safety Sally here if you do get a chainsaw I suggest getting a pair of chainsaw chaps at most you dont need full trousers just the chaps will do and you will have them for a long time as long as you don't rip them.
If you are on a bit of a budget take a look at a brand called Echo they also make good saws for the cash. OK one more thing since its going to be used mainly for some property clearing Id suggest running the saw on Aspen/Motomix for piece of mind.
