Here's a link to the Ryobi trimmer that I bought at Harbor Freight. They go on sale and off again periodically. It's the 725R engine. Thats the long shaft engine and it's easy to convert.

It's a twin ring. It doesn't have the nasty compression relief slots like some of the Ryboi engine do. Thats a good thing.

Get 'em while they are hot!! I paid $49.99 for mine and got it shipped to my house for $58. This is the same trimmer that I got a couple weeks ago. It says "factory reconditioned" but I couldn't see anything on the trimmer that didn't look brand new. Probably a customer return.

I posted links to places to get the conversion parts in an earlier post in this thread. You can convert it for $140 total investment. Thats the engine and all the parts to convert it.

I spent an extra $120 for the C&H--but it wasn't necessary. More for cool factor and weight loss.
