most led's are produced in china or taiwan. the few producers that are not 
from there have comparable prices either, so that cant be the cause.

are you joking? but if you really want to know, that would be a little below 1 
euro, including material & time... after all, soldering one assembly id about 
1 minutes, 2 minutes max. but i wont do that on a regular basis, because im 
not a company.

but the point is not what it costs if one does it in home-work vs. a 
ready-made product. the point is that even for a ready-made thing there is an 
upper-limit, imho. there are quite some other sources for such ready-built 
assemblies..... just look at all these robotic sites&shops. hey, even digikey 
offers to make such assemblies "on demand" and it only costs a fraction of 
the infusionsystems stuff.

what is "my business"? even the cheapest harddisk-led of a cheap computer case 
is assembled that way. its common practice in "that" business.

not necessarily ....

anyhow, that thread got far off-topic now ..... ;)
