Which section? Getting Hardware? That list below has been there since  
I started checking the Wiki Months ago with no real activity.

You seem willing to make these for the cost of components alone. Did  
you add up the costs from Digikey? For me it was (For 10 units):
 - Parts Costs: 500.00 (less the GPS module) + GPS is another  
1000.00 (approx) in USD
 - Assembly quotes for me were (for 10 2-sided Tiny2.11): 609.10
 - PCB themselves (for 10 Tiny2.11 PCB): 105.00
Total for 10 Tiny2.11 PCB + Assembly (includes shipping) = 2214.00 /  
10 = 221.40 each?

I guess if you have the pick-place and your time is free that's  
awesome. I'm pretty sure someone will buy them. I myself am going to  
have 5 made for me at MyroPCB.com I'll post the results. Parts are on  
order from Digikey now. Will take a few days to get them to the  
Assembly house...then 6 days to assemble and ship. So 14 days?

I will have those in about 7 days time on the URL given for "USA  
based" I realized the IR boards are important so I'm having some made  
for myself. I'll just have extras made and make them avail. If they  
are 4-layer it's more expensive to have them Fabricated.

Well, having a commercial venture would not be a bad thing. Economies  
of scale will make costs for everyone go down. If everyone did small  
orders everyone will pay high setup costs. Someday PCB should be just  
a 2.00 and completed Tiny2.11 around 200.00. Then why is the  
"Kestrel" 5,000.00?? :)
