Speaking purely out of cost, Seeed is much much cheaper, even if I have 
to cut the panels myself and even assuming I can't cut as narrow as I'd 
hope and mess up some pcb's.

Seeed charges 9.99 USD for 10x 5cmx5cm. So that's 50 cm^2 for 9.99. 
That's 80 of those mini pcb's. Even if I break 50% from not being able 
to cut properly, I still have 40 PCB's for 9.99 with free shipping (I 
think, but even so).

Worst case, They won't let me have 8 designs on the 1 pcb, and i'll 
strip half of them (to make cutting room) I'd end up with 40 pcb's for 9.99.
