IMHO people tend to overestimate what's required in a tripod.
My first tripod was a $70 Ritz camera house brand (Quantaray). I was on a tight budget at the time. The thing was solid as a rock and produced steady day, night, and star trail shots for years.
The leg locks started getting sticky from too much use at the beach so I end up replacing it with another Quantaray tripod, this time about $90. Again, steady as a rock.
Granted these two tripods had thicker legs and more weight than the other small / thin leg tripods from Ritz or Best Buy or whatever. But I certainly didn't have to spend $200.
When I wanted something for hiking, I got Adorama's FlashPoint 1128 carbon fiber legs plus F1 ball head. This holds everything I've got steady, even for star trails to my surprise (it's a small/lightweight tripod, but is still tall), except for my 300 f/4L IS. And with that it's not so much that it's not steady, but I'm a bit worried about it being too top heavy.
Since then I've come to own a Gizo 1548 (gift from a good friend), a carbon fiber tripod that still goes for nearly $600 on eBay for just the legs. It is a tripod that can hold a super telephoto (i.e. 500mm, 600mm, 800mm) rock steady. The workmanship and materials are top notch and I can see why people spend this kind of money. I love it. BUT...in the end, if you have a more common body/lens combo, and the wind isn't howling, the $70 Ritz brand tripod would hold a star trail just as well.
Now I can't speak to the one you're looking at. But the 5 star Amazon reviews tell me that it probably is not a wobbly pile of scrap metal, and should hold your equipment just fine assuming the wind isn't howling.
FYI, here's the Flashpoint leg set/head I've got for hiking: http://www.adorama.com/FPTPF11281N.html
BTW, the one review noted that a leg "came apart." It's supposed to for cleaning and maintenance. If you're in a hurry and not paying attention you could over twist a leg lock so that it disassembles. I suppose this could be considered a negative. I consider it a positive when I get home from the beach having shot in sand and salt water and need to thoroughly clean the legs.
