Any lupin growers out there?

I am a fan of lupins, not the ones that just make your garden look beautiful,
but the ones that can be eaten too.
 
The thing is I cannot find any sweet variety, and the only lupins Im growing are some Italian 
white lupins (Multitalia) , a landrace of white lupins from southern Greece, and some local 
wild  narrow leafed lupins that are bitter as hell.
 
I know lupins are quite popular in Australia and that there are many sweet vaieties there of 
L. albus and L. angustifolius too. But searching the internet didn't help me find to buy some.
 
Is anyone here growing lupins as well?
 
Here are some pics from L. albus and L. angustifolius plants that I used in my dissertation 
project.

I have grown them before and we have wiled ones here in the spring. never thought about eating them, but the Doves Loves there seeds.
