Before investing a lot of time or money, there are some parameters to consider.
1st - How many items will you have ?
2nd - Do you need the ability to do continuity, upsells, down sells and
cross-sells ?
3rd - How will you take the payments ? Do you already have a merchant
account or will you Paypal, Google Checkout Amazon Payments etc.?
4th - Will you have an affiliate program
5th - If the site fails (the vast majority of ecommerce sites fail) how much do
you want to lose?
Okay, shopping carts come in 2 forms. the 1st is really the total site cms system with the shopping cart as the basis for the site.
--- Aspkin recommends CS- Cart ( $270), Gremlin mention zencart, cube cart and oscart. All good choices, these are all total cms site systems with customize options.
-- Brass tacks - Good options, especially if are going to have a huge site or an affiliate program.
-- Drawbacks
- steep learning curve (zencart),
- limited payment acceptance choices
- no Amazon payments
--- The other choice is to use a different cms-site system, WP, Joomla, Drupal, Front Page, dreamweaver, etc.. and just use a cut and paste code add on cart.
-- Amazon payments, Paypal, Google check out and Mercantec all
offer these Free. (plus hundreds of other providers)
-- Brass tacks
- Super easy to get up and running, If you choose WP you get
all the benefits of a blog (feeds, Linking, comments,
trackbacks) and the ease of use.
- Most of the choices are free (Mercantec, Amazon paypal) to
start using ( no upfront fees)
- ease of checkout - one button push to Paypal amazon etc..
and just enter your email, then approve it.
--Drawbacks
-- Hard to integrate continuity and upsells
-- Need separate plug ins for an affiliate program
-- More time consuming to add new products
-- Need to make up a separate Google base file

Just click the add button and observe the process
So there it is. It just depends on your needs.
Points in favor of using WP and a cut and paste cart, are the ease of checkout.
----Making customers fill out a form before checkout KILLS your conversions.
---- Amazon Payments is adds huge + to your conversions
---- Cheap and easy to get up and running
For my next site, I plan to use WP and just the straight Amazon payments cart.
