Thanks! I'll have a look on eBay. Sounds cheaper than some of the other ones I have found online.
I'm in Canada (Calgary). I ordered mine on Ebay. I am looking at it trying to find the brand name, but it doesn't say and I can't find the old box. However, it says Pocket Fetal Doppler, it's 3MHZ and I remember it was available in different colors (orange or blue I think...I got the orange one). It's basically all white with an orange piece on the front. I love it...I took it to my OB to learn how to use it properly (so I didn't worry myself) and she said it was as good as hers. It has a digital readout too, which I like, telling me beats per minute. It was around $100 US if I remember correctly, and worth every penny to me. Good luck.
