i've heard great things for glass cages (In general, there will always be exceptions) for large tanks, but they don't in general, again, from what i've read, take the same care with custom nanos. there are alot of really good places that specialize in nanos out there, i would pick one of those.
i've heard LOADS of great things about firstclass and socal. can't go wrong.
i think they will both do either glass or acrylic.
