I found the group this FF girl got the info from - they're a BG on babycenter -

I'm not sure about the stats at the bottom... TBM is Turkey Baster Method. I think those girls take the semen, put some drops of lime in it to kill off the boy sperm, then insert. I was reading through that BG - wow those girls are hardcore!!!

Apparently Toys R Us has a centrifuge, maybe not too expensive? (Probably part of some kids chemistry set lol!)
I think if we do TTC again maybe I'll just use b/f as my method - I was b/f when I got preggo with Macy and low estrogen seems to be the big important thing (that's why vitex is supposed to be good - it lowers your estrogen). Amazing the kind of stuff that's out there to try though!
