Had it for around 5 years I guess. Very light use. Maintaining rent houses cutting out saplings. Small jobs for clients. Biggest tree I've dropped with it was probably 6 or 8 inches. I'm hard core as you can tell. Well now I'm clearing a site for my house. 30 or so trees from 8 to 20 inches I'm guessing. I know it's a cheapo saw but it is nice for small stuff so I don't really want to kill it and have to buy another light weight saw. You think it can handle the task with ease without dying or should I invest in a 450 or 455? Bigger chain is less likely to get stuck right? Make quicker work of the job. I'm wondering if the crappy saw will make it harder and more dangerous. Don't want to buy something I don't need but don't want to smoke my little saw and have to buy a big saw and replace my little saw.
