I will hold off for a while, you really need to know what do you like to shoot and how do you shoot. With that information, you can easily pick the tripod that will serve you for a long long time.
I went through 5 or 6 tripods during a 2 year period. I should probably have waited. Then I got a Bogen (Manfroto) that lasted me 15 years.
Btw, I am a ballhead guy. never really like pan and tilt. However, good ballhead tends to be more expensive.
