I got the Sonoline B as well (3mhz probe) from clinicalguard.com. I found a 5% off coupon code which made their price the best I could find. I practiced a lot around 8 weeks and was able to consistently find the HB (with a full bladder) at 9 weeks.
I rented mine for 22/mo from hea.rtones.com and it has been great. Picked them up right away at 9 weeks and have been able to hear them ever since (although now they move around so much I hear that more than the heart beats!).
