Drosera easy growers:
(I wouldn't recommend anglica or scorpioides for beginners; anglica is temperate and scorpiodes is a pygmy)

Flytrap easy growers:
Typical (if you get a typical, I do recommend the ones here
from FlytrapStore, as they will arrive healthy - many stores sell etiolated flytraps) - the hardiness of these vary plant to plant, but most typicals I have are fairly vigorous.
Pink Venus (one of the best-looking all-reds imo, and hardier than Akai Ryu)
FTS Maroon Monster
Sarracenia easy growers:
Leucophylla "Hurricane Creek White" (email David
, he probably has these in stock) - this is one of the hardiest clones out there
Purpurea (ssp venosa, ssp purpurea, or similar S. rosea)
Nepenthes easy growers:
All the neps you mentioned are considered easy growers. A few in addition:
x Ventrata (Ventricosa x Alata
hybrid - both parents are easy growers also)
Ampullaria (these stay fairly small)
If you can keep flytraps and nepenthes alive, you can certainly keep a ceph alive. Just remember to go easy on the watering (overwatering is the #1 cause of ceph death).
Read the care sheets before proceeding; heli's are more particular about their growing environment than many other CP's.
