If you are in the market for a new saw, the first question you need to answer is how much do you want to spend. From there, you decide which saw can you buy that will suit your needs and your budget. I would suggest staying away from the consumer saws, even the ones made by Stihl (025, 029, 031, 039 etc). Sounds like you need something in the 4 Hp range. The Echo CS-510 is priced right, but Echo doesn't advertise their Hp, so unless you could demo one or talk to someone who has compared one side by side with other saws, I'd be a little leary. To get a Husky in that size range (359 3.9Hp, 261 4.2Hp 357XP 4.4Hp, 365 4.6Hp, 362xp 4.6Hp) you are looking at $400-500. The Stihl 036 (4.4Hp)is a great saw, and you could pick one up for a little over $500. If you are willing to sacrifice brand name and still get a quality saw, I would definitely look at the new John Deere (EFCO Made) Saws. The CS-56 (4.1Hp) is just over $300, and the CS-62 (4.7Hp) is just over $400. These saws are good quality, but may lack a little in user friendliness (no side chain tensioner, outboard clutch, no master control lever, no easy off filter cover). They do have magnesium crankcases, carb primers bulbs, decompression valves, and centrifugal air cleaning. Otherwise, some good used pro saws, or sometimes new saws, can be found on ebay for good prices, but buyer beware!
