I couldn't help this one.. apparently the geocommunity (datadepot / thinkburst / qlinks (or whatever the he#$%$# the place is now called ;0) has "DOQs DOQs DOQs"... at a mere $495 per State... nice deal getting these freely available data for a "FINski".... Want to save yourself some $25,000??? Simple to do - check out these free GIS data resources from State clearinghouse sites (most of which contain freely downloadable DOQS, DRGs and more). See the following useful resources for some valuable leads:

Data Directory (100's of pointers to free State data resources) - http://www.gisuser.com/content/section/10/41/
Finally, I can't say this one enough... check out the USDA Geospatial gateway (Free DRG, DOQs, DEMs, and more!) A detailed description is offered up here at http://www.gisuser.com/content/view/1267/53/ or simply jump directly to http://datagateway.nrcs.usda.gov/ and start downloading data.
