Hi Sammi,
The one I use is Clearblue Digital - they are brilliant. The only thing is that they are quite expensive. Possibly you could find some cheaper on the internet - I haven't found any that much cheaper as far. They are very clear and give you a definite result for you LH surge (no line squinting needed!).
As for cheaper ones, there are probably loads of sites on the internet. The one a lot of girls use is 'Access Diagnostics' - I think there is a link somewhere on the TTC Products sub forum above - plus reviews of OPKs.
Good luck - I hope you get your BFP soon!
