Common predicament for many people and really no right or wrong answers either. Decide what your budget is and if you really want new or can live with a used saw (which ~generally~ gets you more saw per $$$ spent).
I have easy access to two very large metro areas (Chicago & Milwaukee) so there are more dealers than you can count, I shop the best deals between them all and am not afraid to buy online either.
Quick 30 second look online and for $400 or less, you can buy a lot of saw these days:
* eBay Makita DCS6401 20" lightly used $399
* eBay Makita DCS510-18 new $411
* eBay Makita DCS460-18 new $355
* eBay Echo CS-450 new $350
* eBay Husky 455 Rancher remanufactured $299
* Farm/Fleet currently running 10% off all Husky saws
* Many quality used saws on the classifieds on the site too
Personally I feel my Husky 353 is the best value and most over-achieving saw I've been around and used, but needed something a bit bigger, so 2 years ago I really wanted either the Husky 359 or Stihl MS361, both new were just a bit beyond my $$$ threshold (preferred new at that time). Local Husky dealer made a very good offer on a Husky 460 & a local Stihl dealer an equally good offer for the MS310. Even though the Husky was a bit cheaper, the Stihl just seemed a tad better put together, better balanced, more refined for what I needed it to do. Scooped it up and have been super happy ever since (well until I just picked up a clean used MS440 to replace it!).
Unless you are sponsored by a brand and they give you free stuff (don't care if it is cars, shoes, chainsaws, or tooth brushes) brand loyalty isn't worth diddly. Find a deal you are comfortable with and run with it.
