Is there any difference between a Unisaw 36-l300 and a 36-l352?

They look identical. There's a somewhat local 36-l300 that's $1,500. I have a 36-944 that I added a shark Guard manually adjustable riving knife. It's ok but a pain on certain cuts.

I can sell mine for about $1,000 and wondering if the 36-l300 is worth the additional upgrade.
