Atten: Guitarist - need your opinion

My 20yr. old son would like your opinion, I don't play so I don't have an opinion.

He just bought a 1980 hand built Mesa/Boogie Ltd. head 60/100 watts tube. With international transformer. He's running this through an Orange 2X12 cab 16 ohms Celestion speakers. He's had the cab for a while.

He has a friend that wants to buy this set-up. He's thinking he might sell if he can get close to enough money to go with one of 4 options.

1 - An original Vox ac30 2X12 combo
2 - Fender Deville 2X12 or 4X10
3 - Vox ac30 custom classic 2X12
4 - Orange ad30

What do you think he should do sell & switch to what or keep what he's got.
Thanks for the help
