I have two duck chunkers, bought them second hand. Made by J Paul. Work pretty well, althought the tri tronics electronics let me down every once in awhile. Simple enough for me to make work. Throws a small bumper about 30 yards, nice arc. Big bumper a little less and then a full size Mallard about 10-15 yards, not really high but good enough for the price.
Also own an upgraded BB derby double. Absolutely love it. Shoots bumpers far enough with heavy loads that I'm not afraid of switching on flower pot doubles. The battery seems to work better than the last and I haven't had to do any programming.
Definitely going to look intot he mini zinger winger. What are those things priced at?
