Hi, No Name.
To ratify what the others have said: The Basic version disappeared a few years ago. I've been using Quicken since about 1990. At first, I bought the most expensive version; after all, I'm a CPA (now retired), so I need the most sophisticated version, right? But I learned after a few years that all the basic (not a pun, just the facts) functionality is in the lowest-priced version. The higher versions offer little more than advice and "tips": tutorials, planners, reports, etc. There are a few exceptions that are very important to SOME users, such as employment taxes and depreciation calculations that can be very valuable to a small business. But since I no longer was in practice, these features were useless to me. The Basic version handled my stocks, CDs and other investments, along with my checkbooks, which was the main reason for such an application in the first place, and produced the numbers I needed for my tax returns. As time went on and computing generally became more capable, the Basic edition became able to handle online transactions, just like the more expensive packages.
So I began buying only the Basic version when updating Quicken every couple of years, and I never felt the need for a higher version. I don't recall exactly when the Basic version was discontinued - I thought it was earlier than 2008 - but I've used Deluxe ever since.
There is a chart on the back of each retail box that shows the bells and whistles added to each version; for 2010 those versions are Deluxe, Premier and Home & Business - in addition to the Starter version. I wouldn't call Starter "useless", but it is intended for those who have never used Quicken before. One of its major weaknesses is that it will not import your data file from your prior year's Quicken, since you have no prior files to import, of course.
One trick that I've noticed is that retailers often HIDE the Deluxe version! Best Buy, Office Depot, Office Max...and all the others, I suppose, will have a large display of Quicken Premier and H&B Editions. But you will have to ask someone or look behind the counter or lower on the shelf to find the almost-hidden boxes of Deluxe. Even on Quicken's website, the Deluxe version was hard to find the last time I looked (not recently). But it was there.
Oh, Intuit uses the same tactics to sell more-expensive versions of TurboTax, too, but the Basic version of that is all you need - at least, if you live in Texas, which has no state income tax. ;^}
