Myke,
Your success depends upon what you are willing to put into your setup and choosing the appropriate species for that environment. You can't really compare growing VFTs with nepenthes as their requirements are almost compeletly different. As one's climate is Temperate and the other's climate is Equatorial Tropical, the temperatures do not change throughout the year by more than a few degrees. The seasons in the Nepenthes region are generally differentiated by "a lot of rain" and "a lot more rain than before".
As proof of their long-term incompatibility I can tell you that I grow all kinds of rare Neps but I'm a total Venus flytrap killer! I don't buy VFTs, Pings, Terrestrial Utrics or Sundews anymore because for some reason I always kill em all after a yera or so. It's likely because my setups are geared towards Nepenthes and their heat/cold and humidity requirements.
Please, before you buy anything decide what your setup will be and look up what plants will do well in those conditions. Ask yourself the following:
If you will be using an aquarium to house the plants how big will it be?
Do you intend on getting a larger tank if/when your plants outgrow this one?
How will you provide lighting for the terrarium?
How much lighting will you provide for the terrraium? All plants have a prefered light level for good growth.
What temperature will the tank or growing area be during the day when the sun is shining directly on the growing spot (or when the artifical lights are on) and how cool will it be at night?
Will the temperatures (day and night) change throughout the seasons by more than 15 degrees up or down? If yes, is there a way you can keep the temperature steady year round? Nepenthes require a consistent and species apropriate climate to thrive (grow and pitcher continually) year round.
If you've heard orchids were hard just think, Nepenthes are "harder", but they are more worth the effort as the rewards are continuous (and this is coming from an orchid nut). The "hard" part comes from providing the correct climate, which as I said at first, depends upon what you want to put into it.
