Id agree, but we dont know for sure where he is from. with the USD... but anyways, you can do a lot with 3 grand, sure thats the price?

If you're going to put so little effort into your post, I don't see why people should put any more effort into doing the work for you.

If you're going to build a machine, you should at least know about what's in it...
