Some really good unresponsive plastic yoyos (all 20 USD) are the Skyva, Wedge, and the Replay Pro. Check them out and see which one is right for you. I think the Wedge is most balanced of the three but it's kinda personal preference. The replay pro also comes responsive if you want that one. The Skyva and Wedge can also fingerspin.

Plastic yoyos are light, and metal yoyos are heavy and spin longer. But for learning tricks, it won't really matter until you get into more advanced play.

The MagicYoyo v3 on Amazon has a surprisingly good pack which allows you to switch the yoyo between responsive and unresponsive by switching the bearing.

Hope this helps :)
