The following is not to dissagree as much as it is to share my experiences:
My first CP I grew successfully was a VFT. I grew it during the summer, and divided it even, and transplanted it like 5 times in a period of 3 months. Yet, however, both divisions thrived...due to my reading about them on the internet. So, there was a bit of trial and error in addition to the reading.
I should mention that I also grew one before in horrible conditions for a whole year. I had it in a bunch of ferns (extreme shade), watered it only with ~500 ppm tap water--and that only when I remembered it. I even kept it in the original 3" pot. I still have pictures of it flowering...but of course it didn't survive that
After this, I bought $70 worth of plants and had my first and only fridge dormancy. This was my biggest CP purchase. With a second 1/2 price and a few death cubes...rest obtained through trade.
So, VFTs can be very hardy, especially for someone used watering normal plants. They can take more salts and sometimes less water than most drosera...not to mention wider variation of temps...maybe even light! Some of the others mentioned can be also.
