This is the best GHD for overall use (yes, you can do more than abs and hamstrings on this). Cost is great, adjusts well, and the pads have a good slope.
The cons to me are the construction of the wood piece under the pads and the pad being a little too soft.
For hamstring purposes the Elitefts is better but hard to adjust and not as great for abs and rotational work.
Can't go wrong with this and its common to find used in good shape for 50-70% of retail, sometimes less.
