Your best bet would be either the Rega P1 or P2, pre-packaged with a basic MM cartridge, to make your "analog plunge" worthwhile. If you like what you're hearing with either of these, you can always upgrade to a P3-24 (with a better cartridge) later on down the line.
Your "old" NAD integrated amp probably has a phono stage, so you should be all set. The Rega, mated with your NAD and Triangle's, should give you a very nice idea of what vinyl is all about, and I think you'll be incredibly happy for quite a while. YES !!!!, getting into vinyl is definitely a smart move, and you do NOT need to spend a ton of dinero in the beginning. I wish you the best of luck, and HAPPY LISTENING !
