call me cheap, but after plunking down $350 on a refurbed 705 I'm trying to avoid even more.

I found a site gpsfiledepot.com which has topo maps of most of the country. using Garmin MapSource I'm able to tag portions of these maps for download to a micro SD card.

question is, is this a legitimate alternative to the Garmin City Navigator maps? anyone used these maps successfully? I searched for gpsfiledepot but couldn't find anything.

apologies if this is in teh 605/705 tips & tricks thread - I looked through several pages but didn't see anything.
