Best way to backorder and win a domain?

Hey,

I have been browsing around and researching backordering. I am looking to acquire a domain, it currently expires in September and is registered by Nominalia a Spanish register. What would be the best way to go about getting it?

I hear GoDaddy backordering is most times unsuccessful and only works if the person forgets to renew the domain you want. So I assume this would be pretty unlikely.

Any advice? Other alternatives I've heard are SnapNames and Namejet. Anybody have experience with these?

Thanks

Update: is Pool.com any good? From what I read it's free and if they get the domain you want then you pay them. Sounds like a good deal.
