I still say, if you're currently using store bought cast H&G 68's, then getting the Lee 6 cavity clone of the H&G 68 is the right one. Sure, you can buy a Mihec for $100 or so and then add handles to it, or a real H&G for $200 used, but for right around $50.00 WITH the handles (bought separately) is a deal that's hard to beat! I've cast the Lee clone, the SAECO #68 & 69 (both H&G #68 clones, one with a bevel base, the other without), and the Mihec, and they all shot the same from my 1911. The nice thing about the Lee moulds is their price. If after you buy it, you find that you don't like it, you're not out a pile of money, and you can always upgrade to a Mihec, NOE, or Accurate Mold version of the H&G 68 later if you wish. I had the Lee in a 2 cavity, then got a SAECO #68, and sold the Lee. Since that time I also got a SAECO #69 and a Mihec #68, and I like the Mihec the best, so I sold off the 2 SAECOs. If I didn't have the Mihec, I would buy a Lee 6 cavity version in a heartbeat.
The custom mould makers moulds, are hard to beat, but they also cost more than most other moulds, and for somebody that's just getting into casting it's probably more money than they should spend to find out if they're going to enjoy casting. I just bought a custom brass 4 cavity mould, and for the money that I paid for it I could buy 3 Lee 6 cavity moulds with handles for each one! I bought it because it's a design I wanted that I don't already have, and I also know that I enjoy casting, so wondering if I'm wasting money by buying it doesn't enter into the picture. If it was my first mould, there's no way I would spend that kind of money. But that's just me I guess.
