If I may offer my thoughts:
I would go with the first shared risk if I were you. It really isn't much different that what my clinic charges for one fresh cycle - $10,200 before meds. And a frozen cycle was $3,300-ish (unless you don't need AH) before meds.
I have seen, here and on other boards, that many times, the first fresh cycle doesn't work out. (It can, but it seems like a lot of times, it doesn't.) But then one or two FETs later, it does work.
Now, I don't mean to get you down or be a "negative Nelly" or anything. Just trying to look at it realistically. I really, really do believe the first shared risk option you have is your best bet/best bargain. I would have jumped on board with that in a heartbeat, had my clinic offered a shared risk program. (They didn't start until I had already had a failed fresh cycle and had begun my FET cycle.)
Best of luck to you, no matter what option you choose.
