Do you definitely need a saddle with a cutout? I tried a Lithia once and it was very painful, for the reason Muirenn cited. My sit bones were on the edge of the cutout.
T-shaped saddles without cutouts include the Selle San Marco Aspide Glamour and the Bontrager Affiity WSD. The Aspide Glamour is 155 mm wide and very firm. I found it uncomfortable because I needed more padding. I'm currently using a Bontrager Affinity WSD RXL saddle, which is not perfect but is very good for me. The Affinity comes in three widths and three levels of padding -- R (most padded), RL (mid-level padding) and RXL (least padded but still not as firm as the Aspide Glamour). I tried all three versions and liked the RXL best -- the others had too much padding in the nose for me, which caused some problems with numbness. However I offered both the R and RL to a friend and she preferred the R, so it may not be too padded for some people. Bontrager offers a 30-day comfort guarantee. One note about the RXL - due to the shape of the rails, you may need a different seatpost clamp, but that can be easily obtained from either Bontrager or any LBS that sells their products, and it would also be returnable if you try the saddle and decide you don't like it.
