Getting RSS into html websites

[LD]

I've seen this come up a few times here, but it always leaves me with lots of questions.

What to use?
Should I avoid Java?
What's best for search engine spiders?
Can Blog Automator do it?

Probably more I can't think of right now.

I tried

http://www.rss2html.com/

some time ago, and the pages were super slow loading...any tips, advice, etc?

Thanks!
