cateye mc100w wireless cycle computer

i've always been looking for a cycle computer, but i never got into it. once i started looking! i found 2 requirements are necessary for folding bike f20-r
1.it's gotta be wireless, coz during the folding process the wire could be pulled and break!
2.back lit, reason to have back lit is because i ride a lot at night.

i wanted mine to have cadence function but it is not cheap, trying to find double wireless it's cost like 5000NT, since i ain't no pro(otherwise why would i buy a folding bike) i could careless about cadence function.

there are 2 brand that's recommended,
SIGMA-a german brand
CATEYE-a japanese brand
so easily i picked cateye, their one and only wireless cycle computer mc100w :P got this bad boy for 1200NT off a seller from yahoo auction in taiwan. it's very cheap because bicycle shop charged 1800NT for it.
