Don't buy stagg stuff. EVER.
Its breaks and sounds like shit, haha. Its true.
Double kick is the thing you want be getting first, being widely the most important thing in your drum arsenal. Go with brands like TAMA or Pearl import, let the seller inform you of th qualities and brands.
And ofcourse what likfisken said, try them out and if they feel right, you should get it. But do think about how it feels NOW isn't hugely important, because you will get used to it later, and maybe it feels more awesome then.
Good luck
