I like the Yokomo's. I used to have the YZ10 Dogfighter that I raced as a child. Then upgraded it to the YZ10 super dogfighter released in 1994 I think it was. Belt drive.
Depending on how desperate you are for a 4wd buggy, you might want to hold out for the new Losi 4WD about to hit the market later this year I think. Kyosho is also developing a new car ZX6 - not sure when this will be released though. The ZX6 seems to have a aluminium chassis as does the Losi 4WD and the motor configuration is similar to the Yokomo's Team Associated B44.
I will consider the Losi when released just because I love the 22 so much
