sirui vs Manfrotto for travelling
From the little i played with it and what i read, sirui quality is actually good.
I generally detest tripods, but I have a sirui t025 and I'm extremely satisfied. it was not easy to have it shipped in europe, but there are some german websites that sell it tax-free; I'd rate it 5-stars for features, weight, accessories and especially price.
Probably, if you are really serious, you wouldn't use the t025 as your only tripod (as Francesco wrote, you may want to consider both a heavy and a travel tripod in your arsenal). however for occasional use, it's absolutely perfect.
