The pumps were behind there for a while. The manufacturer told us the PSP controllers where down because the machine making them broke. Not only that but one guy is making these pumps so they aren't really a mass production product yet so to the faint of heart, buy one or just relax, ya'll will see in time. Time is the best investment out of anything you will do and alot of ya'll will admit that. I haven't had a chance to talk with Gus in the past week on any numbers he might have been able to confirm or deny due to the fact I'm about ready to take a sledge hammer to this old HRVP but its the only thing I got till I get in line and buy one of these pumps too...
