Affordable outer pots

[Grim Tuesday]

So I have a about 30 orchids in semihydro. Most of them are in deli containers which are decidedly not very aesthetic. Does anyone know of a source for nice looking ceramic outer pots that don't break the bank? I'm not opposed to, say, buying an entire case of 12-24 of them if they are nice enough. I'm thinking something around or under $10/per pot.

Second question: How large is it reasonable to let orchids in S/H get in deli size containers? I don't want to buy a ton of deli size outer pots only to find out all my plants need to move up a size next year. Note that I'm asking "how large" here, not "how old" since I imagine "how old" is very species dependent but "how large" is probably a bit more constant.
