Tinted cells mark the better figure on that row alone: more engine, longer bar, lighter, cheaper. A lighter weight is only a win on the same basis.

What owners like and complain about

Husqvarna 120 Mark III

  • One of the cheapest routes into a dealer-supported gas saw
  • Light and neutral-balanced — comfortable for limbing sessions
  • X-Torq engine sips fuel compared to older small saws
  • Sold and serviced everywhere: Lowe's, Tractor Supply, and dealers
  • Mark III revision now runs bars up to 18 inches
  • Cold-start pull count is the recurring owner complaint
  • Plasticky build next to Husqvarna's own 435 II
  • Tool-required chain tensioning feels dated at this price
  • Shares value-tier internals with Poulan — the badge is the upgrade
  • Underpowered for regular bucking of hardwood

Echo CS-310

  • 5-year consumer warranty — more than double what Stihl and Husqvarna give at this price
  • 8.8 lb dry powerhead is light enough for overhead limbing without fatigue
  • i-30 reduced-effort starter genuinely lowers pull force; most owners report 2-3 pull starts
  • Side-access chain tensioner and tool-less air filter cover make trailside adjustments quick
  • Sold and serviced through Home Depot plus Echo's dealer network — easy parts and warranty claims
  • Automatic clutch-driven oiler only feeds oil when the chain turns, so it sips bar oil
  • Only 1.1 kW from 30.5cc — bogs in hardwood over ~12 inches
  • Chain loosens rapidly during break-in and needs constant re-tensioning at first
  • Cold-weather starting can take repeated pull-and-choke cycles
  • Seeps bar oil when stored with a full tank, a long-running Echo trait
  • 16-inch bar option is more than the engine comfortably pulls
