What would you do? Buy the 7310, or a 660 clone?
Most members here put their wote on the Echo, and I totally agree, if money is no object. If a working saw is essentials for your income, choose the most reliable and buy the Echo.
If not - save a great deal of money and go for a good clone.
The 660 is probably the most reliable of the clonesaws out there and it is sold a huge amount of them. There are also quite av few US sellers who check each nyt and bolt prior to shipping to end users.
If you are to sell a saw OEM or Clone, you will not get the same price as you paid for a new saw. OEM might give you 60% if retail price back and a clone 40% back. Do the math and se on what saw giving the most loss in $.
Saws are just a hobby for me and I own to many already. Both OEM`s and Clones. In the 70CC range i have a HQ372 Clone from Farmertec in the Pro series. When bucking i run this with a 20" and 24" sword. The 3/8 chain kept sharp and it eats through without problems. Also have a few Dolmar OEM saws in the same CC area, but the Farmertec/Holzfforma is my goto saw for bucking. So far, just have had to replace a bar nut, but thats my own fault not tightening enough. It`s thirsty and swallows a lot of fuel. Don`t know how the Echo are when it comes to fuel economy vs the 372.
I also have a 660 clone, but it is seldom used as i find it to heavy with its 32" sword.
So my reccomendation would be to try out a clonesaw - the G372xp Pro seems to be perfect for both wallet and needs.
