For a good solid basic cyclocomputer, have a look at the Sigma BC1200 (1600 if you want cadence.) They have a wireless option, and can be mounted on the stem, freeing up handlebar space for lights etc.
As for data logging HRM/cyclocomputer things, there have been a few earlier threads on this .. the two main ones about (Polar S710/720 and Ciclosport HAC4) each have their own unique quirks and benefits.
If you want a two-in-one but don't need data logging and PC download you could try the Polar S510/520 (like the 710/720 but with a uselessly small amount of log memory) or S150. Other brands (Cateye, Ciclosport, Vetta, etc.) also make a few models like this too. You might even consider getting a separate basic cyclocomputer and HRM watch, so you can use the monitor for other exercises too.
