I just received a 12v 30a supply, the same one previously linked to at Amazon:
http://www.amazon.com/gp/product/B00D7CWSCG. After an initial inspection I see no problems, seems reasonably well built. Unfortunately I will not get a change to try it out due to travel through the end of the month.
I'm really not a fan of these types of PSUs with exposed terminals.
Yeah.. I already got a shock from
mine when I reached up to repostion it.
Won't happen again.
It does have a plastic cover that snaps
down to cover the terminals but some
of the spade connector is still sticking out.
