I think that ^^ Vertigo is my fav of the more reasonably priced ones on Alt. It also comes with a ten arm instead of the shower head and with different colored labels. Which they have in stock will vary though.
I like that Dirty Rico one too though, and it seems to be priced spectacularly low.
Hey! I would look into Evolver glass, checkout glastafarians thread on here. He makes amazing pieces for a great price! I picked up a blemished 35 slit bubbler for $150. thick heavy, clean slits and all precise! I would shoot him an email and see what he has available.
pretty awesome karl termini 8-slit disc perc bubbler on boroboutique.com for $199.00. right now they have a 35% off sale for 7/10. would end up being like $130 instead.
