The CZ 35-70/3.5 macro sells for around US$300-400 over here (and those prices are a pretty reliable guide to global prices). I don't know the f2.8 version but it is a CZ so fully MF but that's a great value lens if it's in good condition. Sell off the rest (if the 28mm is an M you may get US$50 for it and more if it's a K28 - again MF lenses) for peanuts and you may be US$70-80 at most out of pocket. Zeiss lenses may be MF but they are mostly great quality. A steal.
EDIT : note I am referring to Contax Zeiss not Carl Zeiss Jena so it seems I have made a mistake here and I'd look at what the other guys are saying.
