I actually have a SAS slide I'm not using. I'll try and dig it out tomorrow (if I remember), and if I do find it, I'll let you know the weight.
I'd be willing to sell it at a good price, if you're interested. I actually really liked it, but due to my decline eyesight, I found that I needed to go in a completely different direction. I bought an XL slide and mounted a red dot on it, which works perfectly for me.
