Has anyone used an outside provider for an ultrasound?

My husband has been deployed for the past month and missed my first OB appointment and ultrasound. He leaves again in late May/early June for seven months. He won't be nearly involved with this pregnancy as we wish he could be. I don't get to have another ultrasound with my doctor until I'm 20wks (I'm 10wk5d currently) so he'll be gone by then. I want to know the gender before he leaves so that we can decide on a name and buy a bunch of things before he goes so I want to go somewhere else for an ultrasound. Has anyone else done this and had a pleasant experience? I'd love to hear people's stories. Thanks in advance!
