PM or e-mail me @ dacooltech@youcanfigureouttherest, how many pcs of which models you want, and I'll get them for you. Can't promise anything but I might even get a better pricing too...
FYI I've been running a 20PI @ 18V for about a yr now, it's a great pump... It's bulky though... I also had a 30PI sent to pH for his test bench... so he can give you more info on that...
On a side note, we'll be releasing new custom 12V DC version pumps soon as well
