I know the OP asked about foam targets, but I have to say that one of the best practice targets going is the Morrell Outdoor Range bag. We use them at our club and they get hammered and still last about a year for the short range ones (<30 yards). I don't know what the retail is on them, but our cost is about $85. I would buy one for home use, but living only 6 miles from the club why bother. These are good for field/target point use.
For broadheads, which I normally shoot about 20 shots a year, a Morrell Yellow Jacket would be good and last me the rest of my life. Of course since I no longer hunt it would last several lifetimes.
