Thinking of upgrading my bar and stem and have the following in mind.

3T Ergonova Ltd Handlebar
3T ARX Ltd Carbon Oversized Road Stem (118g for 110mm)

However the stem is pretty expensive at around £175, there is an alternative which is...

3T ARX Pro Alloy Oversized Road Stem (150g for 120mm)

This one is much less expensive at around £35, there seems an awful lot of money difference for little weight gain.

All experience and advice would be greatly received please.
