Coverting a fairly simple website from tables to CSS - worth it for SEO value?

Hello,

I have a site I've been building for about 10+ years. It's an illustration site and has about 1,000 pages. Over those years, I have added more images and just copied pages and replaced the images and copy. Well, now I have a huge site that would probably take about 3-6 months to convert to CSS. I'm wondering if the folks here think it would be worth it? It's pretty heavily indexed in Google and the other Search Engines. I'm trying to weigh whether or not the hundreds of hours it would take to convert it would be worth my while in regards to how the spiders might view it.

This is an average page: http://www.inkart.net/illustration/wildlife/jaguar/

And, if it should be converted would it make sense to perhaps try and hire someone to do it?

Thanks for your input!

 

I personally would just because I hate using tables for anything other than displaying tabular data although the SEO value from doing this would probably be limited.

 

Ideally you would want to convert it to CSS, but if the site is already ranking and performing well, I would most likely not make the change. Any change to the code is likely to have some impact on the rankings.

 

Thanks. Your input is appreciated!
