the sportys pvt kit is pretty good, or at least the DVDs alone. i picked up just the dvds on ebay for a song, and i used them as a supplement to my ground school and flight training. i think it is great to have multiple treatments of the same subject material, since one of them might click with your brain better than another. i can't vouch for the entire sportys pvt kit as being a complete start-to-finish kit for your private, but the dvds are way better than some of the ASA dvds that i've seen.
the jepp pvt kit is pricey (not as bad as the cessna/king kit though!). you can get the part 61 kit and save some money, since i'm guessing that you aren't talking about part 141 for private. the part 61 kit is basically missing the pvt syllabus (which is like $20 or so if you want to add it on) and has a cardboard instead of metal e6b.

the part 61 kit is ~$50 cheaper ($186):

there is also the cessna/king kit (which is sold at Cessna Pilot Centers) which is sold at the one near me for upwards of $300 if memory serves. it's pricey but many people prefer this kit because, unlike the jepp kit which is 100% printed material, the C/K kit does have a textbook BUT it also has a whole lot of cds for your computer. the kit is primarily designed around computer-based instruction:

the gleim test prep books (for instance the pvt pilot test guide) are extremely popular as study aids for the written test. don't assume that any of the gleim, asa, or jepp "test prep" books are comprehensively covering everything that the jepp or cessna/king private kits are covering.
