I guess you can read my reply to wanabe but yea I think it's a huge diffrence. If you dont see te difffrence in the quality of the rip itself you obviosuly did not smoke a real roor(especially if it was only $150.) The rip is clean, gives a much stronger instant high, and just makes the smoking experience more pleasurable all together. If you dont care about a quality rip and just want to get stoned you may as well buy a 100$ ounce of shake and a 15$ bong at the convience store and rip bowls till your high.
edit: I would never argue against the obvious fact that some bongs are just WAY to expensive.
