How much should I spend on an engagement gift for my Hubby To Be?

LOL it all depends on your cirstances! My fiancee bought me a car and I get to watch it being put together (along with my ring) and I'm buying his car but we're old and we both make enough money to support these things. This is not breaking our bank. If you can afford a white gold ring with "bling" go for it! You should have it engraved with something on the inside like your wedding date or your names.
