If you don't want to mix gas and oil, the Husqvarna is the way to go. They use the Honda engine. Be aware they make commercial and lighter duty consumer attachments. The Stihl and Shindaiwa are hybrids and require mixed fuel.

Hi Canguy
Thanks for the info, that makes a big difference using Honda's engine. You mean it is the 324LDx? Do you know whether they use the GX25 engine same as the commercial Honda's trimmer?
Thanks

Yes and yes.

Thanks Canguy.

I was reading the parts manuel of the GX25 and GX35 after I saw your posting. They are using a timing belt!! Do you have any idea whether they are reliable, do they need changing like rubber timing belt in cars?

Thanks
