I don't think you'll be disappointed... I think it's worth every penny, and I've only watched TMP and TWOK so far. Let us know your impressions when you get a chance to look through it.
I'm a fan of Nemesis as well. Was it the perfect TNG film? No. But it had one of the better space battles I had seen, it was fun to see the characters again, and it was certainly leaps and bounds better than Insurrection.
