The two advantages to the Edge series are the bigger screen and the barometric altimeter.
I used my old Forerunner 301 for both cycling and running until I got my 705, which I wanted solely for the mapping ability. I wouldn't have bothered with a non-mapping Edge. I continued to use the 301 for running until its USB port gave up the ghost, and now I have a 310XT.
If you don't need mapping, and if you can live without the accuracy of a barometric altimeter, I wouldn't hesitate to use the Forerunner for whatever sports you do. Especially if you're younger and don't have trouble with the smaller screen size.
Between the Forerunner 305 and the 310XT, I'm not sure the feature differences are enough to justify the price difference, especially if you don't really need a swim watch and don't use a power meter. Pretty much the only reason I got the 310 is because I have small wrists and there's no way I could wear a 305. (Plus, I'm a gadget w****
.)
