We had ours done about two years ago.
I ‘think’ we got the basic package (may have even been on a deal) for about £60. It included the scan and some A4 prints. We upgraded (on the day) and also got the picture disk for about another £10 (again from memory) which contained just over 50 photos.
The place we had it done was very good / clean / trendy / professional etc and was actually run as a business by a group of (still working) midwifes and sonographers (however you spell it

), so they are still checking for issues etc rather than just impressing you with the technology – The same checks as the hospital but also counting fingers and toes etc
The room had a comfy bed etc and a large flat screen on the wall so it’s easy for your misses to see what’s going on. The noises / heartbeat etc were run through speakers in the room. Nicely decorated, dimmed light etc – quite emotional actually …
We had it done to find the sex as they couldn’t tell us for sure at the 20 week scan. After having it done I would defo have it done again (on the basic package), I wouldn’t pay for the DVD (but that wont be your choice will it ;-)

) My reason ? The DVD is just a recording of what you see. As you will know from the standard scans – a lot of what you see is blurry / in and out of focus while they find the bits they want to see. When they find these bits and set the focus they are constantly taking screen shots, these are the images you get on the picture disk
Other than having my partners name blanked off and being uploaded to photobucket the images you see are exactly has they supplied us on the DVD, they also supplied us a trace of the heartbeat when they did the check in that area
Hope this helps
