Grex 630 vs. 635

[Kris Bjarnason]

I have read multiple threads about pin nailers, and I have made my mind up that I want the Grex. What I can't decide between is the 630 or the 635. Is the only difference in the maximum pin length, or is there something else I am missing that makes the 630 about $50 cheaper? Thanks!

Yea, I think max pin length is the difference. 630=1/3/16ths......635=1 3/8ths.....645=1 3/4ths......and their newest 650= 2" depth. The 650 goes for over $300.
