What kind do you have, where did you buy it, and how much did it cost? I didn't do it last time b/c I figured I'd be OK until I could feel the baby kick, but she never really kicked much and when she was born her heart rate was dangerously erratic. I'm pretty sure I'll be a wreck if this baby is the same, and especially as we approach DD's gestational age at birth. So I want one!
Re: Dopplers
I bought a sonoline b from amazon. You have to know not to panic if you cannot find it right away though. I found mine no problem the first time i tried but not so easily the second time. I love the one i bought and definitely recommend it.

I bought the Sonoline B 3 mhz for $53 on amazon.com. I got my baby's heartbeat with it at 9 weeks, 2 days (although that's early for anyone and probably not because of the doppler itself). It works GREAT, has a loud speaker and you can still plug in headphones. Some of the reviews on amazon weren't glowing, but I've had nothing but success. It doesn't say it online but it does come with a small packet of ultrasound gel to get you started. I've head you can also use plain aloe vera gel...it won't hurt the probe on the doppler.
I should add that I've definitely got some extra padding in the stomach area so it wasn't because I'm a stick that I found it early.
