I've been watching eBay lately and thinking about buying this program from there. Unfortunately, it doesn't appear to be as simple as selecting the best price. I've found at least four part numbers mentioned, all claiming to be the same product: 283652, 358499, 358051, and 358001. I haven't the foggiest which to select. Supposedly there's a retail version, a student version, something called RDF, and an OEM version. A few listings - if you read the fine print - speak of the possibility of being charged a nominal fee by Intuit for an update, and even one spoke of having the support of Intuit but also having access to their support center... almost as though one may not have full access to Intuit. Can anyone shed light on these part numbers? I'm currently using Q2001 H&B.
