New guy here. Has anyone tried one of these Satlink WS-6906 meters? For my RV setup with a slimline dish and swm3 I really don't need a meter, but I screw around enough with an old BUD that for $100 I think it would be neat to have around. I wonder if it would work for directv and if it would require the ASL-1. I know that the accutrac22 or digisat III pro are proven economical options. The Satlink WS-6906 are all over ebay and satpro.tv are selling them.
