What's a good drawing tablet to get? (Thinking about one with a screen)  I been using a iPad for the past 4 years since I lost my drawing pen for my Wacom drawing tablet and I can't get a pen for it ; n ; because they don't send stuff to Canada for some odd reason?  

(PS I lost the pen like 3 years ago, I don't know how though like I feel like when you drop your pen that you were drawing with and it lands on the floor under you then you look down to pick it up and its just GONE like it said "alright you used me too much to day I'm heading out" the rolls away some where thats far away from where you dropped it)
