I don't have first hand experience with either one but I think they both have good reputations. If the IBLCE is letting their courses confer LCERPS then they must be at least meeting their guidelines.
I can't remember who does the HealthE Learning courses and I don't see it offhand on the site, it looks like it's through Australia (which of course there are a lot of well respected bf people there). I think the people that run both that and the healthy children (center for bf) were at the ILCA convention in Boca in 2002 (I know the healthy children/center for bf was b/c I got on thier mailing list there, they offer university BS/MS/PhD level work as well as the week long intensive "CLC" courses.) I know some of their instructor's names, have seen them around the bf "community" and most have publications, etc.:

HealthE Learning would be awfully convenient (online) while Center for BF would be convenient because it's a lot of CERPS in a short time if you can commit to the whole 5 days.
I tried to get my BSN program to approve one of the week long courses through Center for BF for my nursing elective, but they wouldn't do it for various reasons (wasn't b/c of the quality). That's why I'm doing J. Riordan's class - my school is going to accept it, it is online, and it confers 45 LCERPS as well (plus it's with J. Riordan and I knew her book was a big standard).
I am not sure if I'll be eligible for the 2005 board exam or not... I am teetering on the edge of having the hours/CERPS, etc. so I have really got to call the IBLCE and figure it out. I wanted to get it so I would have it before I graduate and look for a job, if possible, plus I was halfway thinking of going to the LLLI convention in D.C. next summer and could take it immediately following it, but we'll see!
edit: PS.. the week long courses seem really expensive but when you compare prices it's not really that bad b/c you are getting a lot of LCERPS. LCERPS just cost a lot of money no matter where you get them - through LLLI, conferences, Journal of Human Lactation, etc... they are all costly... so be sure to keep in mind how many LCERPS you are getting for your money when you are deciding (as I'm sure you are)
