Whew! Ok I'm here. I do check the board every day and chime in where needed. As Lalle said, I'm finishing up my Ph.D. but also in March my son Ethan was hospitalized with pneumonia and last week my husband's business partner was killed in a plane crash together with his companion. So it's been a rough couple of months. I'm most grateful for the women on this site who pitched in and helped each other.
Having said that. The Symphony is the only pump with current research behind it by way of Dr. Peter Hartmann and his team in Perth, Australia. However it's expensive so most moms rent. That doesn't mean it's for everyone. The Pump in Style Advanced is based on the research that was done on the Symphony and much less expensive in the long run for moms pumping long-term. Then there is the Limerick Pj Junior which although doesn't have the paperwork that the Symphony has, is still a fabulous pump because it applies both positive and negative pressure much like a baby at the breast....and until recently was competitively priced with the Pump in Style. Now that the price has gone up, it sits between the Symphony and the Pump in Style.
Probably the main difference between the 2006 Limerick and the newest model would be the noise factor. About 1/2 way through 2006 they were able to produce a more quiet model.
But all three will do the job. The rule of thumb I guess would be if you don't do well with the Symphony, go for the Limerick because it functions differently at the breast compared to the others.
As for the fenugreek...that's a no no during pregnancy and probably not necessary. Better to spend your cash on an excellent board certified lactation consultant. You can find one here:

Hope this helps clear things up.
Best, Lenore
