Thanks. Had a Delta (AKA Daisy 1170?). Not bad but was it Twangy!!! The 640 (I'm assuming that is with PBA's) sounds a tad stronger. And not all lower powered guns are youth or ladies' models. I finally picked up a Diana 24. I recall one lingering on the back wall of a local family hardware store, NIB, for about $125. I would see it and think, "Man, bet that is a cheap, bottom of the line gun." Don't think so now. Of course, the 640 is probably not quite as nice. And, yeah, that 24 is long gone.
