Reply to NanoPad2 vs LPD8 + Traktor S4

Hey guys, all good?

Here's the deal:
I have an S4 and Im looking for something more, I was believein something like the Nanopad2 (I will use to control and, maybe, filter). But I saw some people talking about LPD8, the built quality and stuff... What can you guys suggest me? I like the XY on nanopad2, but I also wanted to use it for drum (I dont know how you guys call that, just a few drum samples) (Maybe the one who cames with Nanopad).

Can you guys help me?

Sorry, my english sucks! I'm Brazillian and I have 16 years old, so, I dont want nothing very expensive.

Thank you!
