Front Rest Decision

I am looking at these two

Sinclair Heavy Varmint AP Windage Right-Hand

$379.99

http://www.sinclairintl.com/shooting-rests-bipods/shooting-rests-tops/shooting-rests/sinclair-heavy-varmint-rests-prod57001.aspx

OR THIS ONE THAT COSTS LESS

http://www.grizzly.com/products/Rest-Slingshot-Cast-Iron/BE1006

Is the Sinclair worth that much more ?

And if I could.....have opinions on both of them if you own either one.

Both are more than I want to spend and I probably don't need that good of one, but would like it to be the last one I buy in my lifetime and have something good to pass on to my Son

Thank You

JEFF

P.S. If I put this in the wrong section U Mod er Raders can move it if you want:bthumb:
