I have the DW735.
Check the dates on those reviews, Kyle. The DW735 had complaints about blade quality when it was first released, but I thought that those were addressed.
Yes I've had nicks in my blades. There is just a bit of side to side adjustment available in the blade mounts. So you can try opening up the planer and moving one blade left and one blade right in the mounts, and see if that will help improve the cut if you do have a nick.
I think the 735 is great for dust removal. I find it very good on snipe -- and I *don't* have the extra infeed/outfeed tables. I wonder how good it'd be if I did get those. I really like the two-speed option.
I have no idea what a Shelix head would cost, but now I find myself wondering...
