Do you trust a < $60/$70/$80 tripod to do the job of holding it up on a windy day?
Unless you don't want to wave goodbye to the hard earned money you put into for buying the camera, I'd suggest you INVEST in something that is stable and will be with you in the long run.
My personal experience, I bought a Fancier/Weifeng tripod. Yes, it's light, but heck, when it comes to supporting my gear, the legs were too wobbly. Ended up investing in a < $300 Manfrotto tripod. Go to the various stores mentioned above to look at the tripods. One other store, K-13 at Peninsula Plaza, but do bear in mind the (so-called) formula I gave you above when looking at tripods.
Also, one other formula, Max Load the tripod can hold should at least be 3 X (heaviest gear [camera + lens + grip + flash] you can think of). Best, bring them all to the store to test for tripod legs' steadiness. When you extend it fully, and hit it, and it vibrates like the strings of a guitar, move on to the next one.
