[font=trebuchet ms]OK, I'm home after a truly execrable day at work. I have a quart of my favourite black'n'tan in hand (no mere pints for this day!), and I've had a look at the VC amps on the Laney website.
Like I said, go bathe your ears in what these wee buggers have to offer. Even 5 Wattts can be loud enough to upset the nieghbors, so don't get sucked into that 'size matters' BS. The 30 Watt job may give you a bit more clean headroom before it distorts, but if you like the overdriven sound (EL84's, oh yeah!) then the 15 Watt amp may be a better choice.[/font]
