Nice price available to my location and look like they could be good to shrink some projects down! Anyone ever tried these eBay specials?

No but I wonder if the interface chip it uses ST7735R is compatible with the ST7735 (nothing immediately
springs out when comparing the datasheets).  The UTFT library supports ST7735 serial from what I can
glean.   Spend some time comparing the two datasheets perhaps?

The ebay URL you supplied contains a download link to a file that appears to contain an Arduino library and example sketches for the device. The example sketches are .pde extension instead of .ino so the libraries may need modifying to work with Arduino IDE v1.0+

After downloading them to check what may need changing and I read they are Adafruit libraries so I suggest getting them direct from them to ensure latest versions. You need two libraries, this https://github.com/adafruit/Adafruit-GFX-Library and this https://github.com/adafruit/Adafruit-ST7735-Library I downloaded and compild them without problem but don't have a display to test them.

Thats great stuff! So basically the cheaper one has no PCB but the slightly more expensive one is ready to be run from an arduino?

The pinout suggest that there is another variant of the board supporting SPI (LCDB rather than LCDA) - perhaps
same vendor has this one too?

I've got this one:
http://www.ebay.co.uk/itm/1-8-Serial-128X160-SPI-TFT-LCD-Module-Display-PCB-Adapter-SD-Socket-/261150773094?_trksid=p2045573.m2042&_trkparms=aid%3D111000%26algo%3DREC.CURRENT%26ao%3D1%26asc%3D27%26meid%3D4648364954718621766%26pid%3D100033%26prg%3D1011%26rk%3D3%26sd%3D280937300096%26

working nice with the latest adafruit's ST7735 library.
The only issue I see is it uses BGR565 color coding (the driver does expect RGB565 coded colors).. smiley-confuse
