A tripod is something you buy for a lifetime, so buy a good one!
This was exactly the same advice I was given when I was looking for my first tripod system. I wish I had thought differently. The Arca-Swiss B1 I have weights about 1.5 lbs itself and is rated for 90lbs. I thought this would last forever even with a heavy telephoto lens. 12 years past, I never purchased a big white and probably will not in the next 5 years. One big mistake I have made was thinking too far out in the future.
Buy the gear that suits your need within the next 3 years and then upgrade as needed. Things are getting better because of better technologies and smarted design. Nothing needs to last for a lifetime. Use your money wisely and happy shooting.
