I own a 234 Holeshooter and also a Magnum 302. I have had the Holeshooter a short time (EBAY purchase) I have had the Magnum 302 for 4 years. I respect both drills and either of these drills will fly from your hands if you are not careful. ,I performed some simple tests on some scrap wood,,I have found that the Magnum has more  overall power. I have "leaned into" each drill my biggest bits. The holeshooter slowed down  (a little), the 302 didn't slow down at all.
