Not being funny dude, but you can't have good flow, new, shiny and cheaps all at once, just not going to happen lol. Have a look on the forge motorsport site for an idea of your shiny, new, high-flow price range.
What makes you think an old intercooler is going to flow less well than a new one? It's not like radiators which can get silted up - it's only got air flowing through it.
