The "buy the absolute best now and save money in the long run" argument is good, but fails to take into account what people can afford right now, or are prepared to spend. Or even what they need.
Sure, S$2000 on a top of the line CF Gitzo, with an Arca Swiss ball head is nice to have, and it will likely last you 20 years easily, probably more, but if you don't have the budget for it now, does that mean you go without a tripod for the next 5 years until you've saved enough?
My thoughts are : buy something good, and if you outgrow that, you can sell it when you upgrade. In the meantime, you have something to use.
