    I have used modified AM-6155 amps on 222 MHz at a couple of different stations, and they are great and can definitely put out 400W on VHF.  Two things I'd note:

a) the fan noise is quite loud. Headphones are a must. 

b) depending on how they implemented the T/R coax relay (I would get details on both of these points before you make the purchase):
     i) you may need to be able to accommodate a few extra inches of depth wherever you install the amp in your station (it's designed for a 19" rack mount)
    ii) you may need an external DC power supply (either 14V or 28V) to power the coax relay.

The owner/operator claims 400+w which is right in line with what I have read up on. It is out of an operational station. The price is pretty reasonable from what I can tell.
