The price of a top flight tripod and head is long forgotten over time.
I got my Gitzo 5 series and RRS BH-55 ballhead in 2006, and it's still going strong, and it's been through hell. It was in many ways my first "buy once, you're done" purchases.
Gitzo are not perfect and l don't know any amateurs who use them. Just read one review on Gitzo and Benro, he had to have 2 legs replaced, on his Gitzo within 10 years, because of cf breakdown. He changed to Benro, which he found just as good but a lot cheaper.
l bought a Benro about 8 years, l got an demo one, half price. It has stood up well so far, plenty of use on beaches and in the sea. All my tripods have last many years, Manfrotto, Giotto and Benro. Manfrotto was Al, too heavy and not good enough damping.
When l bought the Benro, not many others had them, now they seem one of the most popular brands, in the UK.
