1911 Adjustable Target Grips?

I like the Karl Nill grips but don't like the price.  Does anyone else make grips like them (for a lefty), but cheaper?  
I saw the Heretts (more my price), but they don't seem as nice, and I want either checkering or stippling.  I'd almost go for Rink, but they're only fixed, not adjustable.

Any alternatives?

A new member of the forum is building 3d printed grips. no need for adjustment.

A plain set of checkered panels and a stick of kwik wood epoxy.  Won't be much to look at but you can work with it until it feels as you wish, and all for under $20.

Randal Fung custom grips will custom make you a set  from a scan of your hand, google him.
