Given the price difference ($300), and the 20% off, I'm leaning towards getting the Buzz and customizing it to my liking.
But on the other hand, with 20% off I feel like I should get the better more expensive bike to advantage of the discount. Especially since the Safari comes outfitted stock with 2 of the 3 items on my "immediate replacement" list for the Buzz.
Things I'd add/replace immediately on the Buzz (Probably $150 worth of stuff)...
1) Handlebars. I'd like more riding positions, so either drop bars or mustache bars.
2) Fenders.
3) Rear rack.
Things I'd update down the road if necessary on the Buzz (another few hundred at least... wow that brings me up to the Safari price pretty quickly!)...
1) Shifting components.
2) Brake components.

1) Fenders (pretty cheap, so why not?).
2) Brake components (only if I decide to go disk).
3) Front rack (only if I need it).
