If you are using the older RockChucker (not Supreme), the Redding Boss has comparable ram stroke, 3 1/2". It is top quality and sells for ~$100. Unless you are reloading long magnums or reforming brass, you won't be disappointed. I don't believe the newer (Supreme) RockChucker compares well to the old one. IMO, Redding makes better products.

Hornady or Lee? - Sniper's Hide Forums
All Lee products are cheaply made. All are subject to production variances. Some are innovative designs. How much variances influence functionality is dependent on the product. Don't buy on price unless you're willing to accept the compromises.
Research each piece of equipment and alternatives before spending your money. You want to make straight and consistent ammo. It's not necessarily hard or expensive to do so. Powder dispensing will be your greatest challenge. Weighing charges is the cheapest and most accurate way to proceed.
