Answer: It depends on how you use them. They are not to good at range, but when you get within 24 inches with a few boltguns they're amazing. Their tanks are pretty good but they don't have a substantial long range blast template weapon. Their fast attack is some of the best in my view, transports are really good for transports. Overall if you're looking for a short range good heavy support, and good close combat, Space Marines are your best bet.
Another answer: In short no, the space marines are not the best. Each army has both its strengths and weaknesses. Space marines are powerful and one of the most popular armies, but they are small in numbers. Check out each army's strengths and weaknesses. Check them all out, find out which one YOU like best, if you like necrons go with them, tau go with them. Do what YOU want. In short again, space marines are not necessarily THE best.
The best thing to do is buy the codex

NO, Valkries are for the Imperial guard. Space Marines use Thunderhawk Gunships.
It depends on the person who is playing, but Space Marines are considered to be the best all-rounders.

AnswerIt is easy to get 2nd hand if you are in the UK (Wales is the best!).
The Space Wolves are Space Marines.The Space Marines are a genetically enhanced race of human beings and the Space Wolves are a chapter of these Space Marines.If you want to team up Space Wolves with another chapter of Space Marines, for example, Ultramarines, or Black Templars, you would have to check in the codex to see the rules that apply for allied armies.
You can do it yourself, all you'd need to do is add a few spikes here and there, and then it's all up to how you paint it. If you paint on a few demon faces here and there, as well as the mark of Chaos, they'd be convincing enough to pass as Chaos Space Marines.
