Rick,
I've posted this before, but I hope no one will mind my doing so again.  The
color tiles are rather expensive if you buy the whole set in the nice
portfolio, but if you just buy the tiles you want, without the nice notebook
case they are only $15 each.  I ordered 3 of them, I felt I could go without
the extreme light and dark ones and paid $45.  Which while not cheap, is at
least affordable.  I stumbled on this by accident, thinking one day about
what would happen if I bought a $250 set and lost or destroyed one of the
voluble disks.  I called up and asked, they informed me individual disks are
available- so I ordered 3!

Rick,
Yes, approximated Agtron using the tile replications in the back of KD's
book. And yes aware of printing variations in colors etc. Yet, it seems the
most accurate represenation possible with the resources at hand. Even if 10
points off as you say... Would just saying light City be any more accurate?
Not in my opinion. Or strictly give the bean temp? I already know that a
given bean roasted to the same surface temp in a wide time difference will
be totally different color ground. My 470f temp test roasts of Sulawesi in
4:41 versus 12:24 made this very obvious to me.
Yeah, it'd be great if the SCAA offered a reasonably priced Agtron chip set.
Even if not as accurate as the one's produced for the 'pro's'. Maybe like
paint chip samples type.
Oh, as far as me probably being the first of us to get a La Marzocco, I
highly doubt it in my life time! La Marzocco portafilter basket yes,
espresso machine no, could trade one of our cars maybe...

Speaking of which.  Have you tried the ridgeless la marzocco basket for you
Silvia?  When I upgraded it over the stock one, it really made my espresso
improve.  I now use about 16 grams instead of 14 (no more stuck pucks to the
filter screen either!), and it reduced any bitterness from my shots.  It
also fits my 58mm tamper without problems over the ridged one.

David,
Could you please post where you got the basket. i know it was posted 
before, but i can't seem to locate the bookmark.
For those of you having trouble with stuck pucks, may i suggest the use of 
semi (demi, hemi,etc)-pods. These were discussed ad nauseam on alt.coffee 
and thus would be in their archives.
The idea is to basically cut a circle to fit your portafilter from a coffee 
filter (almost any paper filter will work). You place this filter over the 
tamped grounds, mount the PF and then pour your shot. No stuck puck, no 
mess...I use it all the time..

Hey Angelo.  I emailed it directly to listed mail account since it is an
indirect competitor of Sweet Marias and I want to avoid any wrath!

Haven't got around to ordering the ridgeless La Marzocco, using the ridged
LM double. It too is larger than the stock Rancillio...
