The Sabertooth boards are pretty good value for money and they also carry a longer (5 year) warranty- handy for the inevitable reselling.
If your looking at a P67 board then be aware that performance is pretty much the same across any model you might choose. You will pay more for boards with a bridge chip (unneeded unless you plan on Crossfire/SLI in addition to SATA6Gb/USB 3.0 drives), extra connectivity (a second GbLAN, third party SATA controllers/ports), gimmicks (remote OC modules, non-functional heatsinks) and accessories bundle.
Be aware that overclocking with any of the Sabertooth boards can be constrained due to the lower supported memory bandwidth. The P67 for instance will push to DDR3-1866, whereas other similarly equipped Asus boards (P8P67 Pro/Evo/Deluxe/WS Revolution/M4E) can utilize the next divider up (DDR3-2133) for higher multiplier overclocks.
The Sabertooth boards are sold primarily on the strength of their stability, ease of use and lack of quirkiness, and not as extreme overclockers. If you don't plan on pushing a CPU to the ragged edge (this will also depend upon getting the right stepping/batch of CPU and some degree of luck) of the performance spec then it should hold you in good stead.
