Basic Spares impossible to track down

Bought this machine a few years ago and have had good service, I will add that YOU MUST keep the product serviced and clean, - I have worn out two guide bars and now cannot find anyone who stocks something as basic as a new 20" Guide bar for my 4450C. It now lives in its really nice protective plastic box, minus the guide bar, and is gathering dust in a dark part of my workshop. I will probably sell the perfectly good engine unit on eBay.

I am now looking for a new machine and will never buy another Ryobi product again as they clearly are not interested in long term relationships with users of their kit.

I am very dissappointed.

I would like to have been told by Ryobi that when you buy a chain saw with their name on it, that's it, you throw it away after the guide bar is worn out. Ridiculous!
