so do you have any recommendations for vendors who are quite cheap, have the rare and less rare stuff and won't require it?

Have you researched to see if there's a carnivorous plant enthusiast club somewhere in-country (and if you're lucky, local?). They'd probably give you the best advice because a lot of the members here are USA-based so we mainly know how to (or not to!) import/export/ship plants around country and which shops to buy things at.
