Realistically if you want to use a CRT you will need a scandoubler or second hand 15KHz monitor.

They are effectively dead. They dont make consumer electronics anymore http://www.microvitec.co.uk/

You are insane if you would pay $600+ dollars for a 14" monitor

And for £120 you can get a BRAND NEW 15" LCDTV from ASDA.

It has a built in RGB Scandoubler, a VGA connector (for RTG graphic card input) and it works as a monitor switcher to switch between AGA and RTG.

AND it has an analog TV tuner and speakers.

I dont know (why would I?)

You'll have to do some research on the net with that product code.

Although I wouldnt recommend importing one unless you know someone in the uk.

Nope :-(

Lots of Sony branded multiscan monitors dont sync down to 15KHz.

They have to say on their technical capabilities a minimum horizontal refresh no higher than 15(.75?)KHz

All useless... they just tell you how to build the 23-pin to 15-pin VGA adapter (Shiney silver commodore thingy).

Only useful in AGA Workbench using dblPAL and dblNTSC screen modes.

Doesnt work in (most) games or demos.

LCDTV's are effectively the same as an Indivision / Toastscan Scandoubler. It is an EXTERNAL scandoubler.

They usually have OSD controls to change sharpness and other parameters of the scandoubler (like the screw on the back of the Indivision).

If you have blurry writing on your LCDTV in workbench you should try to adjust the scandoubler through the TV menus.

Also using a Workbench "PAL60" screen mode will help.

Choosing a resolution as close to the panel resolution will also help. The internal scaler in your panel will produce less scaling artifacts with a whole multiple of panel res.

So if it is 1024x768 try for a resolution of as close to (half) as possible.

Remember you also have a flicker fixer so using interlaced workbench modes are fine.
