Alternatively, you can check out other sites selling PCBs for DIY such as musicpcb.com or guitarpcb.com to get your PCBs. They dont sell the parts or enclosure but you can easily get them at sim lim tower or other suppliers.
proco sometimes ebenex might have some spare unit or something (two of my rats were from there).
generally simlim but their pricing quite bad. you can ship in at a better rate.
