if you want good clouds,
DO NOT GET AN AUTO-SEAL RIG. if you get 2 or more hoses, make sure it either doesn't have autoseal, or you can take it out. it messes with your O's, and your cloud size.
i personally love mya qt's, they're expandable to 2 hoses for under $20- (mya hose adaptor: $7-$8, and a mya hose is about $7). plus they are washable, huge plus.
i'll probably get one this summer when i get bored of my new km that's coming in tomorrow
if you want huge clouds you're probably going to want a phunnel bowl, and some al-fakher or starbuzz since those are the juiciest brands.
