Curious, I agree that it is best to avoid newchurch icons. From what I've read, much of her 'revelations" are questionable. In fact, I believe I saw some good posts on the subject here on this forum.
For a wonderful image that is sure to bring you many graces, I suggest the Sacred Heart of Jesus. Now THAT is a truly, unabashedly Catholic devotion, promoted by so many undeniably true Saints.
I can affirm from my own life that honoring an image of the Sacred Heart of Jesus, especially the family enthronement and family consecration, bring saving graces.
However, since Sister Lucia of Fatima has said that Our Lord appeared to her and said that He wanted the image of His Mother's Immaculate Heart honored alongside of His, our family enthroned a statue of the Immaculate Heart of Mary besides Our Lord and it is very nearly miraculous the graces that Our Lord and His Mother have given.
When we have such wonderful devotions as the Sacred Heart and the Immaculate Heart, it really doesn't make sense to go for these dubious things. And I wouldn't trust anything JPII did or said. After Assisi, I became convinced that he wouldn't recognize true Catholicity if it bit him.
