I wouldn't recommend the Martin Logan speakers. They are all for looks, and they don't sound great in my opinion. For Paradigm speakers, the V7 was made as a low range option to their line. They are not spectacular in any sense of the word, you are basically paying for the name.
Here is my thoughts on bookshelf speakers in your range...
KEF 5.25" Uni Q Bookshelf Speakers | Q100 | Visions Electronics
Polk Audio 2-Way Bookshelf Speakers - Black | MONITOR45 | Visions Electronics <---these often go on sale so I would wait
JBL Bookshelf Speakers (LOFT40) - Pair : Bookshelf/Rear Speakers - Best Buy Canada
I have last years model of this in Black...
Polk Audio Bookshelf Speaker (TSi200) - Cherry : Bookshelf/Rear Speakers - Best Buy Canada
So those are mid range Bookshelf speakers. I would recommend the last one mostly, because I have it and it sounds great, if you don't plan on adding a sub woofer to your system anytime soon, they have a decent low range. the mids and highs are great on there as well.
Test the system out with your own ears! Try your own music on it and see if it sounds like how you like it to sound.
