I've not used a Saec 308 arm but I'm in agreement with Serge on this. As far as being heavy, it would suit the cartridges that I use and am looking forward in the future to use. I know my friend uses one with a Denon DL-103 with great results on his Garrard 301.
If I found a really good deal on one I'd add it to my collection.
