Yes they did do jets. The 1121 Jet Commander. Later bought by IAI, re-engined and lovingly referred to as the "Jew Canoe". Westwinds are perhaps the best bang for the buck for anyone buying an older jet. Cheap to get in to ($300K gets you one), built really tough, no major AD's and have great range. The Westwind II will do 3000nm, no problem.
Most people think they look weird, but I think they're sexy as hell with that low slung fuselage and mid wing. The twin front wheel is the icing on the cake. Looks like a hot rod to me.
