hey, I live right next to A2Z, this store with a yoyo team. One of the guys there created mastermagic.net, which is a good site for learning tricks. I was into yoyoing for about 6 months some years ago... got to the trick called "spirit bomb" and never got past it!
Brands like yoyojam and yomega make pretty good yoyos. There are two kinds, string trick yoyos that will stay down until you pull them back up and looping yoyos which come up more readily. Both kinds are used for different kinds of tricks. If you're starting, get one of the beginner ones (I got a kickside, I think from yoyojam), for like $15 (think that's a lot? well you're WRONG!!! hehehe...). Definitely check out mastermagic.net.
Hope this helps!
