Yes, all the time.  Our vectors are p-Bluescript based and we have found 
the material obtained from the Magic minis to be easily sequenced.  

Just for the record, we've found the maxi and mega preps can be used with 
cosmids grown in Terrific Broth.  From a liter we were able to get enough 
material (400 ug) for a prep digest.  We prefer CsCl for cosmid but we were 
in a pinch and just gave the Maxi a proverbial shot...

Hope this helps...
