Computer for an Argon E112

I just picked up an Argon E112 and need an “inexpensive” bike computer. I love my Specialized Turbo Elite but I am concerned about it staying firmly on the fork. Suggestions?

If you are using cadence then that will effect your choices. The chainstays are so tight to the wheel that it leaves a huge delta between the stay and the crank. I use the Cateye v2c wireless. If you just need speed, then many choices should work on the fork, it just takes a longer zip tie.
