It's a 10-15 minute fix if you have the tools.

Take note...in the Park Tool photos, they are working on a Specialized bike. The only reason I mention this is most of the complaining seems to come from Cannondale folks...like only Cannondale uses this.
Seriously, if you are that averse to entering a bike shop for service, then buy the tools and do it yourself. Like I said, it's maybe a 10-15 minute service job. If you know what you are doing.
The bearing press tool, if you shop around, $150-$160.
