i have the classic cast turret also.it works great,is inexpensive and fast to change calibers.the pro auto disk powder measure is o.k. but not very precise.get the pro measure,dumping out unused powder is a snap and you will need the double disk kit (2 powder disks on top of each other).remember,you are limited to about 50 grains of powder (approximately) per drop.i have a dillon 550 and wouldn't dream of buying conversion kits for more than a few calibers($$$$$)plus changing calibers on a dillon is a real PITA...
