I'll second that opinion. How 'tube-like' they are depends on the model and your personal opinion. I own a Pod XT, and used to own a Pod Pro. While not exactly like a valve amp, they are close enough for my uses. I'm more than willing to forgive their minor shortcomings due to the fact that you can get fantastic sounds in pretty much any style of music very easily without annoying anyone else in the house. You can play such devices through home stereos as they have line level outputs. Also, you can plumb it straight into your computer should you wish to record; they really are great fun. For your uses, sounds like you might not need an amp at all.
Vamps are £100 ish, Pods about £200 and Pod XT's around £300. Your ears and budget should tell you which is for you (if any

) Loads of other floor based pedals do amp modelling nowadays, so you might want to look in that direction too.
If you definately want an amp, the smallest valve amp I can think of is a Cornford Harlequin at 6W. Played one a couple of times, and really liked it apart from the lack of reverb

Also, no headphone socket and it's over £500 IIRC. Not sure if the Laney LC15's have headphones on them, but several folks on here have them and like them.
