A $200 new CS-352 would be awesome. When I bought one earlier this year the best prices I could find were not far off list. I ended up buying one from the good local dealer during an Echo sale for list price, no tax and an extra chain.
I use the 352 for brush clearing. It's light and starts easily, which is important for me as I make a few cuts then pull brush out of the way (it's thick brush). I prefer to turn the saw off then start it again for the next few cuts.
The fuel and oil openings are small. The air filter lets dust into the carb. But my brush cutting is dirtier than cutting trees would be. The air filter's probably ok for that. I added some oiled foam fitter material in the air box covering the carb adjustment holes which appear to be the main path for air into the box.
I removed the catcon and the carb limiter tabs and retuned the carb. The power gain was not dramatic but hopefully it runs cooler and lives longer. I'd buy another one.
