You are definetely looking at the right bikes. Couple of other suggestions that are better climbers would be the Turner Burner on closeout for $995 at Supergo (3.6" travel) and the Titus RX-100/Hammer Head 100 with 3.8" of travel. Both use 100mm forks and are comparable to the Blur. The other bikes you listed are designed around 120-130mm forks.
