We currently use a version of SCRUM that's more align with the traditional sense. BUFD and phase development just doesn't work. I would recommend reading Agile Patterns and Practices before adopting it on a new project. It will convince you that Agile is the way to go, and gie you ammunition against the nay-sayers.
Don't be afraid to customize the process. Our customers and stakeholders get afraid of the Agile terminology (Pigs, Chickens, sprints, planing game, etc...) so we've renamed them to more conservative names like (developers, stakeholders, releases, planning, etc...). Also, for our teensy tiny team (1.5 people), the daily stand-ups are too many. We have it weekly and call it a bug scrub. Essentially, we're prioritizing our iteration and product backlogs.
