The AEK-4T kit (which includes the LEA-4T) is $349 from the UBlox site

The LEA-4T module is available separately in the online store for $179

I don't have time to look right now they also have an LEA-5T for the
same price -- new and improved??

I just phoned Navtechgps.com and they have the development kit for the
Magellan AC12 for $995

When I asked if they sold the module without the full development kit,
 the salesperson refered me to this model called the DG14 for $1995
