drupal 6 and Paypal

Hello,

What is the simplest way to integrate PayPal into a D6 website? 

I see that UberCart can be set up for PayPal - but I've never used it and from a quick look at it, I'm wondering if it's MORE than I need for simple way for non-tech users to make payments using PayPal. 

Is UberCart the best way to go, or perhaps lm_paypal, or even the e-commerce module?  This is my first dabble into online payments, so I'm trying to keep it as simple as possible!

Thanks for any suggestions!!
