Samick makes some nice stuff, but on my Phantom I found it cut only too center, not past center, so for my arrow choices and style of shooting I had to mod it.
Same for my Tradtech Pinnacle 2. It went on the Dremel diet and feels close to a standard Blackwidow grip now 
Never had to mod any of my Blackwidows, their standard grip fits me perfectly.
Like others have said, you need to try before you buy, as feel/grip is everything.
FWIW I picked up a badly twisted PSE Coyote, fixed it and changed the grip, smoothed the riser, and twisted it to reasonable brace (factory recommendation is too low IMHO).
Twisting it up to where it isn't tooth rattling, is quiet........adds some poundage. My 50 # is nice now, but hits 55#@28".
Not a great bow, but usable with mods. I run a Hoyt Pro grip on mine. Made a huge difference in feel (had to mod grip a bit). Stock Coyote= sucks. Cheap one modified= usable.
