I seen a homelite model about 12 years ago. But, haven't seen any since.

I saw one at Home depot on the endcap this weekend.
It is pretty heavy though...

I would have to say that the solution to your problem is not to find an electric start trimmer. I have always found that if a person is strong enough to pick one up, they are more than strong enough to pull start the machine providing it is in good working order and well maintained. I say start fresh with a good quality new machine, and keep the servicing up to date and you will have no problem. Good luck.

I should have added with my first response but i have an echo trimmer where you can pull the cord as slow as u want. As you pull it winds up a spring or something and when the pull cord reaches a certain tension, the spring kicks in and then spins the motor.

If echo still sells this, maybe you might look for this feature. It makes the trimmer lighter than what i saw at the store.

If you aren't apposed to Craftsman, they have what is called Sim-pull. Essentially the same as the 0utsider has on his echo. Several other manufacturers have this also. It makes it unbelievably easy to start your trimmer or other 2 cycle engine. You don't have to yank the cord, just pull it and it does the work for you.

Tanaka made an electric start gas powered trimmer.
