Best Bicycle Computer?

[Bill]

I am wandering what the best bicycle computer would be based on the following:

Most accurate in the programming (i.e Speed, Miles,etc)
Lowest Price
Battery Life
Weather Proof (Getting Wet, Cold Temps)
Display (How visible it is in both daytime and night)
Ease of use ( How easy it is to use)
Durability ( If it gets dropped)


Any suggestion would be helpful, Thanks

Bill
