If you're a Ronnie James Dio era Rainbow fan like me, you'll want to make room in your budget for the new 2-disc "Live At Dusseldorf's Phillipshalle" finding the boys at the top of their game in 1976.  Said by many insiders to be the best sounding live set ever released by this classic line-up, with clean remastered sound and an 8-page booklet.  Blackmore, Dio, Carey, Bain & Powell smoke through the whole show, unedited.  It's an import so be prepared for nearly a $30 price tag.  Check it out, sounds worth it to me!

A record company promo still of the boys:
