500 watts RMS might just be enough.

The Yamaha seems quiet for the specification and is not cheap.

Avoid the Fender suitcase-pack like the plague.

The Peavey suitcase-pack is not bad, but has not got enough inputs for you, and may not be quite powerful enough.

The Thomann is not bad.

Much to my amazement the Phonics sound quite good for the money, but do remember to put any piezo pickups into the ultra HiZ inputs.

You may find a second-hand Peavey 680S PLUS (must be the PLUS, the 680S has not got the power) at a sensible price, as they have been around for a while, and although I am not usually a fan of the Peavey sound, which tends to be thud at the bottom, but scratch and tizz at the top without much tone in between, they seem to be relatively road-proof.
