Decided to go with the Sigma. For under $20 for the wired version it's cheap enough to see if I even really want one.
Exactly my thought process when I got mine. And I do like it. The only thing I can see that the Strada has and the Sigma doesn't, is that the Strada seems to be a one button type operation. At least I think so. For a basic computer, I didn't find one that could beat the 1009. And I over research everything.
I did have to go to the hardware store for an extra o-ring, as I have a large fork and an oversize stem, so I needed two big ones, and it comes with a big and a small, but that cost about $2.00. And you can use zip ties instead if you want. Installation and setup was easy.
BTW, I took the advice of someone here and put a drop of grease (oil also works) on my tire, then rolled the bike and measured the distance between the marks to determine my tire circumference. I did it twice to make sure, because it was so far off from what the manual said for my tire size. I suggest you do the same. It's really easy. On a 20 or so mile ride, my computer is often quite a bit off from the distance of other peoples' readings, but it's right on with the guy who has a Garmin GPS, so I think mine is correct
Hope you like it. I'm very happy with mine.
