If you do get a cup and cone bb, be sure to regrease it every now and then unless you buy one with seals around the spindle. Unsealed bottom brackets like the stock one you had depend on the grease to catch any grit that gets around the spindle but if it gets wet or oiled or wet with soapy water that can emulsify the grease, or even if it's just not regreased often enough, the grit will work its way in to where the bearing balls roll.
