Hi-Si's are nice for their price, and so are Hvys (heavy). I have a Zob bubbler that's nice and thick, and all of their tubes/bongs I've smoked out of have been just as nicely blown.
From the sounds of it, I'd get a straight tube with maybe an extra perc on/in the tube it's self. Then add an ash catcher. As for those, pretty much anyone will do. They all function about the same so don't blow a bunch of money on that.
Sorry I can't get you any links or exact names of pieces, I'm on my way out the door for a weekend vacation
