My needs are basic: given that I mostly use MapMyRide (etc) to measure my commuting or training routes, my primary need is the autostart/stop for timing purposes (I don't want to fuss with a cellphone or stopwatch for this).

My only other needs are: inexpensive and availability of mounts for other bikes (although, if the cyclocomputer is cheap enough, I may not worry about other mounts).

I don't care if it is wired or wireless although, wireless versions of wired models tend to be more expensive.

Suggestions welcome, please!!!

Cateye Velo 7

^+1
I really like the Cateye Velo 7. Large display, easy to use/program. $30.

I run a Bontrager Trip 2 wired on my road bike, because the cheap analog wireless computers tend to go haywire next to my Cygolite headlight on any flashing mode. It has settings for 2 different wheel sizes to be used on different bikes, although there's only 1 odometer. Fine if you want to track total overall miles you've ridden, but not so good if you're like me and like to track miles on the bikes themselves.

Sigma BC16.12 or BC14.12. I have a 1609 which is very similar to the 16.12. It's waterproof...tested by sending it through the washing machine more than once. It has second wheel mount which is a nice feature if you have more then one bike. It also has cadence which I never use. The 14.12 looks interesting because of the altimeter feature (no cadence). Both of the computers have second wheel capability. I highly recommend the 16.12 and may get one of the 14.12's soon.

I recommend the Schwinn computer that I got from walmart. (it has the normal stuff of trip, odo, max speed, ave speed, time and temperature) and I have used this on my bike in the rain with no problems and it cost about 10 dollars...

gives picture (though the listed price is higher than what I paid)

Although not inexpensive, I love my Garmin 510

me too. Something to think about; you have a few bikes, and you can use it on all of them.

The display on that one looks exactly like the one on my Bell wireless computers. I have 2 of them but only use one of them. I'm probably going to stop using the 2nd one and get another wired Bontrager one because of the interference issues with my front light when it's on flash mode.

I have a Garmin 500 and really like it.

Just wanted to note that I haven't had a problem with mine (a wired version). one of them died recently, but I have had it for over 5 years now and I should have replaced the battery before it started leaking..

I certainly wouldn't spend much more for a basic cycle computer as its not really worth it. I have had avocet, cateye and they cost twice as much and didn't fare any better in terms of length of life...

I use a Cateye Strada wireless. You might also try an app like Runkeeper, which is pretty darn accurate.

one that lets me input the actual radius .. but any cheap one will do .

Now antique Ciclomaster went on my touring bike I liked that I could hide it down on the fork blade.

O ring sealed metal screw-down battery cover .. I only used the Odometer counter.

I got this model for $18, and it has given me no problems so far.

I am still running an old ~ 2003 Cateye Enduro 2 on my Trek and I have a Cateye Micro Wireless on my Gunnar.

Both have been reliable and easy to use. I haven't tried many others because Cateye has earned my repeat business.
