If I had not colets yet I think I would go for one that took R8 then I would compare exactly what it cost to get the two with R8 to my door. and get the cheaper one . they are prety much the same thing.. just my oppinion.
grizzely has a nice heavyer duty one for like 999 and I think you can find it for free shipping, but that may be too costly or too big for you..
well just my 2 cent..
