NHS 20 week scan wern't able to tell me the sex so paying privately. This place in west malling seems by far the cheapest but I'm wondering if there's a catch to the cheap price (e.g. old machinary not as accurate etc). They also tell me I can get 3d pic of baby at the scan for no extra charge (bit dubious as to if they do this as it doesn't say so on their web site). Web site also doesn't give their sucess rate for gender scans. Any good/bad experiences? I need to book soon if I'm going to as they are getting booked up...
