I agree that they're not light, especially compared to a small gas powered unit. But, the Echo addresses three out of four of the OP's original criteria very well.. It will last for years, probably decades,( especially with light residential use ) It's quiet, powerful, and it's not a PITA to keep running. Another aspect to consider, not just with the Echo, but any Li-Ion powered tool.. Compared to gas powered, over the long haul, they're pretty much free.. Ten bucks worth of gas and premix per year, for 20 years. plus no tune up or servicing.. You'll NEVER... Buy gas... Buy and mix 2 Stroke oil Buy Stabilizer Throw out gas, gas / oil mix because it won't run right. Drive to the gas station to buy gas Replace the clutch Replace the spark plug Pay for a tune up And that's just the stuff that costs you money.. It'll NEVER... Not start Not run right
