Im 30 weeks and also live in IL but I know that Goldenveiw is also in TX. They have days where you can schedule on certain days and get a discount. Also maybe you can ask a family member to get you a 50 dollar gift certificate at the place of your choice. If your having a shower or even if your not. Then you can invute then with seems you can have up to 7 people in the room
I live in northern IL, I thought they were expensive also so I didn't really look in to it and I'm glad I did! I did a Google search of 3d ultra sound and the town I live in, I found a place that did mine for $129.00 and I got a 30 min session, dvd, more than 60 pics, cd with all the pics, heart beat recording and a goody bag...and, I'm going for my free session tonight because my pkg comes with 30min free session if you don't see the baby's face. She kept get face hidden with her feet and the cord last session. I was 28wk, now 30wks so I'm super excited :-)
