I performed a search and came up with some answers, but not all.

I currently own a GL1 and shooting a documentary. I'm looking to purchase either an XL1s or a refurbished XL1. Can anyone advise if there is a noticeable difference in the footage captured between the three cams - particularly between the XL1 and the XL1s (the search told me that there is little difference between the GL1/GL2 and XL1s).

Any assistance or comments would be appreciated.

Mark,
I either own, or have owned, all of these cameras, many simultaneously. In general, you'll see a greater difference between the GL1 and GL2 than the XL1 and XL1s. Still, I highly recommend the GL2 or XL1s. Each has significant enhancements over its predecessor.

Thanks for the input, Ken. I own the GL1, my brother (who is also shooting the doc with me) owns the GL2. The funds available to me when I purchase may dictate which cam to buy and I'm probably not smart enough (ie: have enough experience) to take advantage of all the bells and whistles. If there isn't much difference in the captured footage between the XL1 and XL1s, then that helps a great deal.

I can get a refurbished XL1 for around $2500 so I'm leaning towards that.

Thanks again.

I've edited XL1 and XL1s footage together from the same shoot, and cannot tell the difference between them.

Thank you for the info. This has helped a great deal.
