How is AliExpress for long-term availability?  I've always been=20
concerned that they're somewhat like ebay... having items available only=20
for a certain time.  Do you have any experience to support the contrary?

So far I've used smaller TFT LCDs with controllers/parallel interface=20
(ILI8341, ST7789, etc), but for this larger display I'll be using a=20
PIC32 so finding a supported controller or perhaps going controllerless=20
with LCC is my preferred direction.
I yet have to research the differences between drive methods (parallel=20
RGB, vs. VGA, HDMI, or even SPI).  I have a perception that SPI would=20
not be fast enough to show quick changes (say 20-30 frames per sec at=20
VGA resolution), but that's just a perception until I try it.  For now,=20
I'm ordering a 7" SPI LCD to tinker with.

Cheers,
-Neil.
