Yes to LCD. Even if tomorrow you could get a used FF from Ebay you could use the VGA port with it (if the LCD is equipped with one.

And BTW. if you have ECS or AGA you could mode-promote and inject the video to VGA instead of Scart.

I guess you need the extra Hi-rel laced for some serious work, else why bother removing the flicker on modes usually used by games?!?

There is another tip - if you get yourself a VGA splitter, you could feed both RGB and SCART inputs from the RGB analog channel of the amiga, something that is quite convenient, like having a multiscan monitor.

Of yourse, the success story would include a test on the site to see whether the TV can cope with the odd sync rate of 29.92KHz instead of normal 31.25 of VGA 640X480.

Amiga's ECS and AGA have the VGAONLY monitor driver that brings sync even closer to VGA than doublePal.

All the resources the DBlPAL modes consume are AGA resources, ie making refresh slower (a big pain if you are into Graphics or music editing.)

CPU Processing power (especially on an accelerated a1200) remains almost intact, that's amiga's magic.
(no IRQ to hold back the CPU until refresh and leave you with non-responsive cursor, as seen on XP.... :-D )

by the way, if you are up to the trick with LCD's bear in mind that lcd's are less tolerant to odd refresh rates than CRT's, hence my probing for "try befory buy".
