I have a Salsa Big Mama which is a full suss 29er. Very nice it is too.
Using my hardtail 29er for the winter months now though as there is less to get ruined by the mud.
The choice for full suss 29ers is far lower than for hardtail 29ers although more are coming onto the market now. Gary Fisher have a decent range, as do Kona and Niner. Other full sussers seem to be from bit more niche companies such as Lenz, Salsa, Ventana. More big players are dipping a toe into the market though with the likes of Spesh, Turner and Santa Cruz.
