I used more sandpaper than that on my lapping. I went to autozone and I bought 2 packs of large (10x10) assorted (200/600/800/1000) and cut each piece into 3rds (total 6 pieces of each grit=24 sheets). I don't think that 5 pieces of 4.5x5.5 will do.
What I'm trying to say is that 8 bucks more is worth getting it done. Of course it is cool to say you lapped your own.
Their customer service rocks, too! I'm sure if they did fudge it up, they'd pay for it to be shipped back and redone.
