It's not as obtrusive as you may think. If you look at the more modern systems (see the first link in provided above), it's a pretty minimal single post and narrow box rail, with a relatively sleek, modern looking car system. You could also make the vertical supports visually appealing if you invested a bit more in aesthetics (but yes, Halifax is always cost averse).
