Looking to get a phone from wind mobile?

Im looking to get a phone from wind mobile, with a spending limit of $150-$200.

They have this "as low as $0 WINDTAB" on three selected phones, if you choose the $40/m monthly plan. It offers unlimited talk and text and also data, which is great because i cant get enough of tumblr. But ive never been on a windtab before.

I just wanted to know if this seems like a good deal? Does wind have hidden fees i should know about? Is there a better deal from other carriers?
If you've ever been on the windtab thing, is it good? And also which phone seems adequate?

P.s I text everyday, and make some few calls now and then, and then theres tumblr.

P.s.s Whats your opinion of wind? Ive read some reviews both good and bad, but overall is wind anything like rogers or bell or telus?

P.s.s.s Sorry for asking so many questions, i just really dont want another phone company sucking the life out of me.
