The last few weeks I have seen them last for at least 10 mins. They go live right around 7:30am PST on Saturday mornings. Have an account registered with them in advance, that way your CC and shipping info is already there. Once they go live, throw that thang in your cart and check out.
I've been watching the site and they are lasting longer nowadays. The Borotanks tho?, that's another story...
Well, I followed your advice, created an account in advance, and boom, I'm the proud owner of a Fawkes (really sad I did not see that a TNMBB was also available, but what the hell). A big thanks to you, man.
And now trying to find a Boro...
