Lb, that's a broad question with many answers and opinions. First, before you go out and spend $500 on a new saw, what is wrong with your Husky? The 55 is a well made saw and has a good rep. If it won't run it's almost always the carb or fuel line. If it has sat for too long the crap Ethanol will clog a carb in no time. Fuel and impulse lines degrade over time and crack. They cost about $6 a peice and a carb kit about $15. Use Marine Stabil (the green stuff not the red and Wallyworld carry's it) in all you small engines....it is one of the only fuel additives that kills ethanol.
Some of Huskys smaller saws are re-branded Poulans and don't hold up quite so well. Stihl does not re-brand & I would say their smaller saws are of a better quality. Stihl & Husky's larger stuff is pretty much equal quality-wise so it comes down to personal choice.
The first saw I ever bought was a Stihl 024Super in 1983 and I still use that saw today. Before I "
saw the light" I almost sold it for parts. Then I found another website that has a dedicated saw forum and learned that I just needed some knowledge, a carb kit & a fuel line to make it run like new. I know own 7 Stihls(down from 12, and I heat with wood) and have bought and sold a few more that I rebuilt/repaired.
So, if you want to try and fix your saw go here and post some questions. These guys will help you out and determine whether the repair is worth it, or to go shop for a new saw:

Now for the opinion, fix the Husky, & buy a smaller saw for light work. I never go into the woods with less than 3 saws. One large, one small for limbing, and one Back-up saw in case I make a mistake like hit a rock or metal, pinch a bar in a limb(or heaven forbid in a tree:ashamed
