FS: great hybrid for new/heavy rider

I love my lavender Diamondback Edgewood hybrid, but she's just too small. I think the frame size is 15". I'm 5'8" but she's probably better suited for someone considerably shorter. She's been a great little workhorse/grocery getter for about a year and a half (about 1400 miles). I've replaced her cassette and she has a new chain (within the last 200 miles). I also replaced the rear wheel with a beefier Bontraiger race lite wheel. There are some scratches in the paint, but other than that she is in great shape. optional items include a blackburn computer and a rear rack suitible for holding two grocery bag type panniers.

The basic setup was about $450 when new. I'm asking $200 , but will consider less if I'm satisfied she'll be going to a good home. I will deliver within a 25 mile radius
the 2006 version (which looks exactly the same to me) can be seen here
