Depends on your needs and taste. I have a WGS Vet 30 in mine and it shines for all my applications. Usually a Mesa Subway Rocket, Fender Pro Jr., or Vox AC15 (though this needs altered mic placement to be as friendly) through it, and I recorded parts for a record using a Carvin X100B @ 25W through it too. Shone every time.
I found a really good deal on a Fane A90 so I jumped on it. 90 watt Alnico made in UK. Saved about $60 off what they wanted for the Celestion by going with the Fane. Saved $75 off the cab through Reverb. Free shipping and an Avatar tee shirt. All in all... a good day.
