Projections and Extents?

So I'm trying to modify the unique value renderer example and one thing I don't like is the projection of the US where the Canada US border is flat.

So I found this example of this code to add instead of the normal gray basemap from Esri.

It works in that it's something new but it's not in the projection I want.

I found the list of WKIDs but how do I find the extent to go with it?

extent: new esri.geometry.Extent({xmin:-20098296,ymin:-2804413,xmax:5920428,ymax:15813776,spatialReference:{wkid:3088}})
});
var dynamicMSLayer = new esri.layers.ArcGISDynamicMapServiceLayer
("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/2")

Eventually I will use my own server but for now this is testing.

Thank you in advance,
James Cucinelli

I believe you'll need to use a GeometryService to project the webMercator extent into the projection of your choice. Maybe this sample will steer you in the right direction:
