Kegs: Stainless vs Plastic

I've been doing a lot of research regarding kegs. There are pretty much three directions we can go. Buy brand new kegs from a distributor via China, buy used kegs off of an other brewery, or buy new plastic kegs.

STEEL KEGS

Pros: Durability, preconceptions that the beer tastes better from steel, highly conductive, cheap when used.

Cons: Heavy, high scrap value, home brewer's delight, expensive when new.

PLASTIC KEGS

Pros: Light-weight, stackable, made in California, will not be stolen by devious home brewers, reasonably priced when new.

Cons: Misconceptions about taste, not as cool looking as steel, slower to cool down, cannot be turned into a brutus brew system.

What do you think? Plastic or Stainless?
