Yep, Preyhunter's right. In addition, the VA only allows lenders to tack on certain fees (which keeps them from tacking on whatever fees they want). Tends to keep closing costs reasonable.
I got lucky two of the three times I did a VA loan... the rates were lower than conventional mortgage rates. From what I understand, this is not always the case - VA loans often have a slightly higher rate than conventional ones.
EDIT: You can also move in for no money down using a VA loan. However, be advised that you must pay a higher VA funding fee. The funding fee goes down with a larger down payment. I'd recommend putting down as much as possible to get the funding fee down as much as possible.
