I'd certainly go for a Black Diamond one. I use the Transfer 3, and I've never had a problem with it. There isn't a huge amount of difference in the BD range other than weight and the length of the handle tbh.
Once you pick one, I'd suggest getting some wire to go with it, so you can loop it through the holes around the edge of the blade. You can use this to hang it outside the your pack American style if you want, and to use the blade as a deadman anchor or fluke. Using the handle for a T-cut anchor should be simple enough with just a regular sling.
Good luck with the assessment!
