Sigma - BC 1606L Cycling Computer @ Cell Bikes $39.95
Whereas the last cell cycle deal was a laugh this is here because its a good price.
Its touted as the top of the range Sigma (not that that means a great deal) but in any case it has all the basic functions you need - except GPS to tell you where you should have gone.
Nearest other prices are $55 up to $120 so the price is worth a look if your in the market for one.
