I clicked the link and the first thing I saw was a titanium spork

, that is so PLAN9 I'm gonna order 12

On a more serious note the Swedish fire steel is a good product, but a little expensive there. You can pick up the Military type magnesium firestarters normally for under 10 bucks, and we used to get hot hot sparks (the same thing listed there, only with a BSA logo in the handle) in Boy Scouts for about 3 bucks. A good firestarter to use for these is dryer lint in a waterproof container. Dryer lint of course is free and it catches fire very easily if you fuzz it out.
The emergency kit in a can looks useful, but I prefer to put my own together in Mil-surp pouches or altoids tins. You can build the same kit cheaper. Look at what's inside and build one just like it. Pick a day if you can to go hiking or camping and see what you used and what you wish you had taken and build from there. Another hint, although most everyone favors matches, I prefer a cheap cigarette lighter, they're tougher and you can light more fires. The small Bics run .79 cents most places and even when the fluid runs out you've still got a striker to use with dryer lint.
The Travel toiletries look interesting and worthwhile, but I've never used that particular product.
The compact grill looks awesome, but I'm a bit of a sucker for "cool" stuff like that anyway.
The survival kit in a water bottle is a good idea, but I would just use a large sports bottle and make my own. Luckily that site has large detailed pictures so it would be easy to see the exact contents to duplicate kits like that.
Without reviewing the whole page I'll just say some of looks useless or overpriced. If you have any specific products or uses you have Questions about, post it and I'll try my best to help you.
