I’m a big fan of the ColorFabb filament, and honestly Voxel Factory is great! If you look at what the Europeans are paying for the same filament, we’re getting a great deal over here in my books.
It’s completely worth the money in my opinion, and I’m a student who’s broke 
95% of my issues disappeared when I started using ColorFabb and got my printer settings tuned for the filament.
Not nearly as cheap as other options, but certainly a high quality product with zero headaches, and that’s worth a few extra bucks imo.
Cheers
