Homebrew PCBs

The Shurflo 2088-343-135 data sheet states 8.7 L/min at 2.1 bar.
The Shurflo 2088-422-444 data sheet states 6.4 L/min at 2.1 bar.

I did a google search and found the link below is to a place 
selling the 2088-343-135 for US$69. Its cheaper for me to 
get dilivery to Australia , since the best price I found in 
my city for the Shurflo 2088-343-135 was AUD$240 (US$150).
If I build another spray machine I'll get this pump.
