Most reliable Guitar Hero guitar controller?

I have heard the ones for Guitar Hero 5 and Warriors of Rock aren't very good... I would like to know if there is an affordable one that won't break. I want Warriors of Rock but the guitar in the bundle has gotten bad reviews about the strum bar.

GH3 Les Paul is probably the best. I also like the GH2 Xplorer, but Les Paul is wireless which is always nice.
