My understanding of the strobist concept is that it's fundamentally focused on being able to do high quality, professional looking lighting 'on the cheap' and to demonstrate how inexpensive older, manual flashes suddenly became a powerful tool and could be used to build a kit for little to no money.
TMR, you've got this totally wrong, Dave used to have a huge inventory on SB-24, 26 and 28s and he wanted to drive up the prices before selling it off on the ebay 

The prices of those things doubled since he started the strobist blog
.
On a serious note I think the ideal strobist type setup for canon is
1) AB400 (for studio work as main light, great with light modifiers), $230
2) 580EX II (fill/backlight in studio, E-TTL if ever needed, outdoor off camera flash), $380
3) vivitar 285 (fill/backlight, cheap). $90
Canon 540EZ
