I think the correct name is "SuperDish Repoint Kit" and is suppose to convert the SuperDish 121 to a Dish 1000+. It is listed in one of the small books the retailers have that was dated last summer (Jun 2006?). Since the Dish 1000+ uses different LNBF's than the regular Dish 1000 to pickup the sat at 118.7, the kit would include a new LNBF cluster and some mounting hardware.
Since the 121 and 105 uses the same dish pan & arm, I believe such repoint kit will work on either one.
Last week, Claude (The DishStore) mentioned on another thread that he hasn't seen them yet.
I've been waiting to buy 2 of them.
