There are 30 Claridge townhomes from the mid-90s on Forward Ave and Lyndale in Mechanicsville, and there are even nicer ones a block south, but the Soho Parkway will block out the sky from their backyards.
The Lebreton Flats townhouses are a little older, but fairly nice and tend to go in the 360s-380s.
These places here are right by Hampton Park and the listings I've seen tend to be more reasonably priced (always in need of updating though) http://maps.google.ca/?ie=UTF8&layer...,0.013583&z=16
There are some smaller townhouse infills scattered around Carlington too, which are a bit more affordable, and could be desirable as Carling and Merrivale North slowly improve... over the next century! ;-)
Good luck; townhouses in the urban area at entry-level price points are crazy competitive (don't be surprised to see a dozen other bidders driving prices to 10% over asking)
