Did you buy a new CBEFM? Or did you get a used one??
I really want to get one, but I don't think I can spend $200 right now so close to Christmas!
I bought a new one from amazon.com. I also got two 30 day packs of sticks. All in all it was about $200 (+).
Here is one for just over $100 including some sticks. https://www.amazon.com/Clearblue-Easy-Formally-Clear-Plan-Fertility/dp/B000WGE40Y/ref=pd_bbs_5?ie=UTF8&s=hpc&qid=1228068816&sr=8-5
The overall cost is better I think, and it takes the guessing out of the OPKs (which I can never read)
