Thanks Jarrad.
What width do the blades start out at? They did look a bit thin on this one. I didn't measure it but they looked to be about 20mm by eye?
I will keep looking for a bargain. Problem is, you don't get time to post a pic/link etc if it's a good one because they sell too quickly. At least I got my old 33 going again so I'm not in a rush anymore.
Cheers
