I have a mostly love / occasional frustration relationship with our Francis X5. It produces delicious espresso but the proprietary (and non-standard sized) tamper and shower screen made a trip into the garbage disposer recently and we needed to find a replacement. If any of you have been on a similar search let me save you some trouble. If you call Illy America they will transfer you (unsuccessfully the first time) to Cafe West. Once you are in their hands they quickly and professionally ship you a new tamper and shower screen for $15 including postage. To contact them directly:
As far as I can find- there is no other place in the States to find a replacement. Please post a followup if you know of an alternative.
