I'm looking for a cheap, preferably sub-£30 composite/S-video to VGA box for running my A1200 through a TFT.

I'm sure this has been asked umpteen times before, but my searches only dug up references to more expensive (£60+) models, and if I'm going to spend that kind of money I might as well chip in a bit more and wait for a second hand scan doubler to show up.

Any pointers?
I got an E-Tech tv box, wich works very well :-)
But you might also opt for this, wich definately will get you the best picture quality. (RGB 15khz to 31khz for $48, though it needs a very little soldering around)

Well, you just need to get yourself the 23 pin connector (not available in store anymore, though you can remove 2 pins on one side on a female 25 pin connector with a iron saw, and then you can ask the builder for a pinout, get yourself the pinout of the Amiga on HwB and you can solder it straightforward, without additional stuff).

It works because it's analogue.

Have you tried one with an Amiga or know someone that has?
I have soldered alot for rgb/s-video/composite stuff. I know this works because it's the right format.

Look at this`
Amiga video pinout
and this
CoCo
It's basically a job of rewiring. :-) (Soldering the Grounds, R, G, B and Horizontal + Vertical syncs of the Amiga to that of the CoCo, so to say)

Yeah but the Coco3 only outputs 64 possible colors, many fewer than an Amiga, and normally the ADCs/DACs and memory in a scandoubler have to take this into account. Besides that, for only $48 it's too good to be true.
It can be done for 20 euros but it's a lot of soldering.
