I have done the "taco" method using the Arista Premium tank from Freestyle. Four sheets fit quite nicely using the cloth-covered elastic bands sold for holding a woman's pony-tail. The tank require quite a bit of develop to fill, but you can get around that by using a dilute developer and doing semi-stand agitation for a longer period of time. The only caution is to make sure there is adequate developer to develop the four sheets (about the same as for a roll of 35m film).

I use HC-110 dilution G (1+119 from 6ml of syrup concentrate).
