There is also the 5300c with an Active Colour 640x480 LCD, which is far superior to the other colour LCDs except the 800x600 in the 5300ce.If you're not planning on collecting a pile of PowerBooks high enough that you really shouldn't try to stack them . . . :-I . . . I'd go for the 190 if you can bring it back to life. I'd also go with the grayscale display.
If you wait to find a 5300ce, it's already at 117MHz and the first PB ever to sport an 800x600 (beautiful active matrix) LCD.
With the two of those, you'd have the Alpha and Omega of that 1995-1996 product cycle case design.
You might want to get the 190cs, 5300 & 5300cs later. Definitely do so if you ever get your hands on the almost, but not quite, unobtanium Mustang ProtoBook. It was either the testbed for the 1400's larger display, the Low End Mac for the 1996-1997 product cycle or both, but never shipped.
Even without it you'd have:
190_______Passive GS
190cs_____Passive Color
5300______Active GS
5300cs____Passive Color
5300ce____Active Color & 800 x 600
Giving you every LCD/Processor example of a unique series in a compact 10.6" stack or 12.8" should rope a Mustang. One of our comrades has a Mustang in his corral . . . [] ]'> . . . no, it's not me . . . [

I have also heard of a failed attempt to put a 5300ce LCD on a 190. I believe the issue was due to VRAM.
