Protein shake or Meal replacement

Evening, i used to be on USN meal replacement shakes (http://www.ebay.co.uk/itm/USN-Diet-Fuel-1kg-UltraLean-Low-Fat-Meal-SHAKER-/221039233446?pt=UK_Health_Beauty_Vitamins_Supplements&var=&hash=item3376f709a6#shId) and as you can see its pretty cheap. The only thing i dont like about this is it has 17g of carbs. Im trying to reduce carbs. Also im having trouple getting the right amount of protien so it would help

Should i stick to this or go to a full on protein shake and if anyone could send me links of any they use, in the similar price range (im a student)
