which file guide?

[wally 12]

I like to hand file my chain, I currently use a stihl hand held guide.
I want to get a bar mounted guide or maybe even a bench mounted ,the one that stihl offers is a little expensive. Is there a big difference in quality and useability from the Stihl brand and the other brands?
Can anyone make any suggestions on which one to buy?

Howdy Wally, I been looking at the Granberg G106B from Baileys. But I've never used a bar mounted before.
Also there is an Older one on Ebay now too (G106) I'm not sure if that one is an earler version or not. Anyone know?
