I see folks occasionally looking here for decal sets, so I thought I'd throw this link out there. I recently ordered a set of decals for a '97 from a company called VeloCals. http://www.velocals.com/servlet/StoreFront
They currently only produce them for the '96-'97 factory and for the 2000 Homegrown and Homegrown Pro, but the 96-97 downtube decals could be used for '98 and '99's as well as you get to specify what inner color and border color you desire. Also, the factory top tube decal on the '96-'97 set can be cut and rearranged for non-factory models before you apply them.
Also, I encourage the addition of the UV top coat option as it truly gives them a factory look when applied. Got mine applied a couple days ago and am pleased. The font on the downtube may be just a tad bigger than original, but it is nothing anyone would notice unles you put a tape measure to it.
Overall a very good source for those in the need.
