Immaculate concept on 17'th ave is considered to be one of the best shops in town. I don't personally have any work from any of the artists there but I know a few people who have gone and are extremely happy.

Deadly tattoos on Macleod tr by chinook is another good shop with a bunch of great artists working there. It is also the shop that James tex works at (Owns?) who is considered by most to be one of (if not the) best in tattoo artist in Canada.

I would also suggest checking out Dustin Poole and Ryan Gagne at Sacred Balance tattoos on 17'th ave by 14'th st, I have some work done by Ryan and am extremely happy with the result.

as for price, If you're looking at something small (Wallett/deck of cards size) in Greyscale, from any of those shops I am guessing they are in the 150-200$ range. Remember good Tattoos are not cheap And cheap tattoos are not good.
