I'm very close to pulling the trigger on a Gaggia Pure. However, a few health concerns I've developed regarding the model are off-putting to me. I really wish I knew more about these machines (for example, the exact path the water takes from boiler, or reservoir, to cup when you pull a shot) to make a decision.
I noticed the use of aluminum in the Brew Group, which stirs a little worry in me with regards to alzheimers, etc. I can't really figure out from the coffeegeek glossary whether or not the "brew group" actually makes contact with water during the pulling of a shot? Does it? Or does the brew group merely hold the important parts that do?
I also noticed that the included portafilter is chrome-plated brass (which might mean copper contamination if it cracks) and has plastic spouts. But, does the portafilter itself really make contact with the coffee? Or is it more the filter baskets inside? Gaggia doesn't seem to indicate the material of these baskets in their specs section. Anyone know? Might anyone have experience replacing the spots with something nicer on this specific portafilter? Or going spoutless (without espresso going all over the counter)?
Finally, does anyone know if, besides the reservoir, the water passes through many plastic parts (especially when heated) in this machine?
Thanks for reading coffeegeeks and health nuts; I hope someone with knowledge/obsessions in both areas can help me out!

According to the information I found on the Pure it has a stainless steel boiler. I used a Gaggia Classic everyday for five years and now my daughter is using it. It has an aluminum boiler with the two heating elements outside embedded in the aluminum. I like the Classic better than the Pure. Its recycle time is fast between shots. As fas as the chrome plated brass they are bullet proof portafilters and unless your going to use it to beat your way through a concrete wall with a chisel you will be fine. It has no issues. As to your questions regarding aluminum,copper and stainless steel and potential leeching into water that has been discussed here at length with no real conclusions. Seems that everyday millions of Americans drink from aluminum cans and are still alive. If I were you and you can spring for it I would get the Classic and MDF grinder combo as a basic unit.
