RichardNow you're talking my language!
About 18 months ago I started down this exact same path, and decided that I would try to collect 1 example of each pre-1920 Toronto card out there. Excluding Colgan Chips, I have checklisted 26 and managed to obtain 24 of them.
The sets that they are in include:
N172
T206
T201
C46
M116
T213-2
T215
As far as affordability, you should easily be able to get a T201 and some of the C46s for a reasonable price. O'Hara, Kelley and McGinley are tougher (ie. more expensive) C46s. You won't see too many Toronto N172s, the T213s aren't bad (I got my Tim Jordan on eBay last year for less than $20, though it is beat), and the T215 is somewhere between the T213s and the N172s.
There are a bunch of post-1920 sets that feature Toronto as well.
My site is VERY MUCH incomplete, but if you want to see a gallery of the 24 pre-1920 cards I own check out the gallery at http://www.torontobaseballgrounds.com.
