[NTG-context] (Most) stable minimal for Mac Intel

Hi folks, after hesitating for a while I've decided to take the plunge and dive into LuaTeX finally. I'm just a bit confused about what the most stable release of LuaTeX is at the moment and where to get it ... from Pragma or the garden? There is a minimal distribution dated 2007-08-08 at Pragma but it appears slightly outdated ... shall I still get this one or is there a later version which also runs more or less smoothly? I'd be glad if someone pointed me to the "right" minimal ... by the way, my machine is an Intel Mac equipped with Leopard. Thanks for your help, Oliver
