I'm in New Zealand, and am a big fan of Oleo Mac, made by Efco. I'm normally a Stihl guy, but in my opinion the Oleo Mac are every bit as good as Stihl and Husky, although they seem slightly heavier. My main Oleo Mac now I'm using is the GS 650, a 65cc saw, pro build, damned good saw which runs very strong for 65cc. I use it usually with a 20 inch bar and chain (3/8 by 0.058) and in softer wood like Pine it has plenty of grunt, is responsive, easy starting as well. I did find it needed 20 or so tanks through it before it started producing great power, and a muffler mod and tune after this transformed the saw.
For a bigger saw I use the MS661, with 42 inch down to 25 inch bars. The Oleo Mac is a perfect in between saw, and personally I can't stand anything under 50cc because they seem too gutless, even for limbing.
Just my 2c worth, but here the GS 650 came in at least $600 cheaper than the equivalent Stihl, and has proven to be 100% reliable, and strong for its size. As mentioned it seems a little heavy, but its all metal pro quality. The anti vibe isn't up to Stihl quality though.
Personally I'm at the age where I'm over paying too much for Stihl and Husqvarna, and find the Oleo Mac does the same job for less money.
We also have the Efco brand here too, exactly the same saw in different colours.
Not sure on prices in the States or Canada, but I paid $2400 for the 661, $395 for an Ms180 two years ago (which is such a horrible saw, gave it away) and the GS650 cost me $990 18 months ago. I now just use $140 big box store throwway saws for limbing, much better than the small Stihls.
