Given your price range, you will have to look to the used market. Given that, you really should cough up the twenty bucks for a subscription membership to realskiers.com. Even though the reviews have gone downhill with the new format since the site was sold, the old reviews, which will be of interest to you are excellent. For example clicking on 2012, then Fischer, you will see, according to the symbols (which they explain), that the Watea 84 is suitable for all speed ranges, suitable for blue and geen level "new style" skiers, and old style expert skiers (. That's just one example. There are hundreds of skis that would work. All you need to do is frequent, used ski sales, CL, Cajiji, etc., and when you find a ski for sale look it up on realskiers.
Given that you ski west coast Canada, snow will usually be soft, wet, and deep, and spaces wide open for the most part. So I would not recommend the same ski for there as I would for Ontario where ice and hardpack are the usual conditions. I have skied Mt. Washington on the island, and groomer skiing there is more like off-piste skiing here (off-piste skiing there is like heaven). There is often 6" or more fresh snow on top of the groomed runs. Something mid 80s with a turn radius of 18-ish turn radius (like the Watea 84) would work well there as a one-ski quiver.
If you use the historic real-skiers reviews as a guide, buy a ski with all speed zones, as high a range of skier abilities that still has your ability, and around 18 m turn radius. If you want to learn good technique that includes good carving I would also tend to minimize rocker, but if you plan on going off-piste, then rocker is not such a bad idea, but you would also benefit from a wider ski in a quiver for that.
Hope that helps.
