Proper version for investments

I have investments (stocks and funds and ETFs) and thus dividend income and capital gains and losses.

Can this truly only be reported using the Premier online version ($35 per return) and not with the Deluxe version ($21 per return)?

Similarly, if I get the downloadable version (TurboTax desktop), do I need the Premier version ($83) because the Standard version ($38) cannot process investment related items?

I'm not sure if they have drastically changed the pricing and product offering, but in the past I have used the CD version that was about $45, and it was able to handle investments.

Finally, if I am able to report investment income/losses with any of these versions, then what do the more costly versions have that the more economical versions do not?
