Hi All!
Finally I have found an equivalent of the upscaler sold on eBay (unfortunately only in U.K.) and tested by Dylwin:

That is generally available in many EU countries, as it is sold by Conrad under order no. 989271:
"SpeaKa Professional SCART and
HDMI/
HDMI converter"

I bought it today afternoon. It works well with my QL (RGB-SCART cable) and Samsung LCD TV/Monitor (
HDMI). I can feed the VGA input of my monitor using a HP
HDMI->VGA converter connected to it's output.
I have put some pictures of the different screen modes here:

The best modes were the 720p and 1080p when using the RGB input. The 800x600 mode was blurred, the 1024x768 was a little bit better and so on... I got the worst picture quality using the AV composite input from the SCART cable. (This unit uses the standard SCART BLANKING signal for composite<->RGB selection.) Of course the
HDMI->VGA conversion decreased the picture quality and the picture was blurred as for the 800x600 mode.
