Replying to Street Art

So today I was at an arts store in Boston. I've seen a ton of awesome street art online and such and thought it'd be sick to get into. My cousin actually just graduated as an arts major and kinda talked me into buying just some Krink paint markers so I can start tagging and stuff. Tagging sounds like I'll have fun with it for awhile but I would've wanted more to buy some spray paint. Problem is, I don't know what to buy or how to even get started. If anyone has some advice out there I'd gladly like some help. I'll be the first to admit I'm not a very good artist, but I definitely learn things fast and with a little practice I can get really good at anything I put my mind too. So I definitely want to get some spray paint, let me know your thoughts on brands and such. Thanks a lot guys.
