My vote would be for Moldex as well, one neat thing about being in the biz is you get your hands on some neat stuff. I sourced a new 948 Sprite unit from them about two years ago, it was on the shelf and I had it in a matter of days. A year later I ordered another one and it took almost three months, so the advice to plan ahead is a good idea. I also had my hands on a few Fardon Engineering billet cranks out of the UK, nice pieces as well, looked totally different than the Moldex cranks, I heard even greater nightmares on wait times from them. Now I'm speaking about about MG/AH A-series cranks, can't really vouch for anything else, but I like the Moldex design better, it was about the same weight as my lighten stock wedge A-series cranks, but had huge counter weights and hardly any extra material around the journals and that's exactly what you want in a billet crankshaft.
