I believe you can order that issue for delivery through Paizo's website. If you want to download some stuff to see whether you will like the look of it, go to Paizo's site and download the Age of Worms Overload document as well as the Online Support document for Issue 124. There is an entire forum for the Age of Worms adventure path where you will get hundreds of tips and hints for the adventure(s). Peruse those as well to see what you think.
Ummm... I thought the preference of the OP was for 3.5.
Nothing at all against C&C which I think is a handy simplified system, but I prefer 3.5 out of the two. I enjoy the preparation, complexities, options and defined ruleset and copious support for it. I suppose what I'm trying to say is that everyone's fun is different and besides, the ruleset used did not seem to be an issue for the OP, just the quality of the module.
