A/C - finish out factory setup or install aftermarket?

[HomerJ]

So, I've read a bunch of posts about upgrading vs repairing/refurbishing the factory item. I already have a compressor, hoses, drier and a few other parts. I would need to get a new evaporator and condenser and possibly a poa valve. On top of all that, I'm not real crazy about the factory brackets (Not to mention the behemoth housing under the hood!)

Would I be better off selling my current parts inventory and going with an aftermarket setup?

Are the aftermarket brackets any better? I have the type that bolts to the water pump and intake manifold (the part I don't like).
