oh balls dude, thats an insane deal! and dude, definately ignore jaydee
you'll be able to do anything jaydee can and many times more 1/16" EM wont be a problem(anything smaller may)
Well I suggest you read up a little, get some aluminum scrap, get rid of that peice of cardboard on the table and a 1/4" end mill or bigger and take less than half the diameter of the cut at maximum with regular end mills.
Its looking like it might be a fun machine, I wish I had something like that!
