Slightly nicer, in my opinion, than the CRP-5 is the Aviat-617, which is the Rolls Royce of whizz-wheels.
It also unfortunately makes the CRP-5 seem quite cheap. I was lucky and got one on eBay for £40, which is the only real reason I used it for my CPLs.
That said, for the CPL flying, I found a Pooleys CRP-1W perfect, because you really really don't fly over 200kn, so don't need the big jet tool, and if you did use it, would be mucking about in the corner rather than using the whole scale.
