High Energy DJs - Rants? Raves?

hi ladies, FH and i are picking our last major vendor--and it's the DJ. i saved this one for last, because for me it's the most important. (for some it's photo/video...others flowers...but MY people gotta have some MUSICA!!)

I got a pretty decent price quote from Ralph from High Energy DJ's and was wondering what's the good word on him and his company? Anyone heard or or used him? (Need honesty ladies--I'll be back for more when I start interviewing them!)
