I'm in the same boat as you at the minute Ross. I just bought a job lot; one Stihl 041 AV, one Stihl 08 S and one Husqvarna 50 Rancher. The 041 I've already got running, the 08 S will probably never be resurrected as there's more missing than there is there, but the 50 supposedly only needs rings and looks in good condition for a saw of its age. I have another 50 that I've never yet got to run properly. Always get sidetracked with the next new one!
Anyway I only paid 34 GB for the lot including shipping, so if I get the Rancher going it will be worth it.
