Both are used but in great cosmetic and working order. I built them for myself, but have waaaay too many amps and preamps and have to move some.
First up, the IIc+. It's a single channel, so no channel switching is available, thus the price is lower than parts alone. But you can bypass it with an external true bypass or A/B box. There are no electrolytic caps anywhere in the amp that degrade sound and eventually dry out. Used much bigger and expensive poly film capacitors across the board, together with some paper-in-oil capacitors and other quality parts. Steel chassis is powder coated in cream with brown fender knobs.

Price: 130 euros + shipping from Serbia
Next up, my Tube Reactor which is modified Matchless Hotbox brought closer to JCM800 sound. Two channels, pristine clean and crunchy marshall-y overdrive. It's built into a larger stompbox format, but power supply is in a separate unit built inside a PC power supply enclosure. Power supply is not very pretty (shown below), thus smaller price, but the stompbox itself is purdy
And you can reuse the power supply to power another preamp without investing in expensive supply parts (transformer, filter capacitors)

Note that both operate on 230V, so USA folks would need a travel step-up adapter.
