Eye exam for contact lenses

[hahathor.livejournal.com]

I generally buy my lenses on-line cuz it's cheaper, but need to update my prescription. Most of the previous discussion seems to focus on who has good product available (esp a good selection of glasses frames). I don't need that, just someone who will examine my eyes quickly and cheaply. I'm carless, so within 5 miles bike ride of Davis or on the Red Line is preferable. I went to Harvard Vanguard last time, but wasn't really impressed with either the service or the prices (of course, that was nearly two years ago, things may have changed).
