Replying to Transaction advice?

Hey ns,

I'm currently in the middle of a transaction and I need your advice.  I'm buying a dslr from Sven824.  I have lots of feedback and people who can vouch for me (you can check my feedback).  He doesn't have any feedback, friends who can vouch, etc.  I'm not saying he isnt legit, but It's just kind of hard to get over the idea of sending the amount (which is alot) straight up and hoping everything will go well.  I offered to send half, and then send the other half when I receive the item and he wasn't liking the idea.  Ideas?
