Hi Luke, for your immediate needs, almost any saw will do. You won't be making a mistake wether you buy a 346 or an 044.
More than anything, it's the chain that counts. Once filing has been mastered then other things can be done to increase performance, such as muffler mods where the most significant gain is found, keeping in mind that the faster the saw, the better the dirt works.
Don't be duped into believing that moding the saw beyond the basics is life threating to the motor.
Anyone can hog out ports, turn down jugs, advance timing, etc., etc., however, if all these things don't jive, then what you will have is a loud gutless saw with a short lifespan.
So as you can see, it all goes back to basics. Using a well modded saw with a dull chain is tantamount to driving a car with the parking brake on, so it's all in the chain, then the motor.
I'd be doing your own basic mods first and playing with the filing aspect and gearing up the saw so you can see your own results.
