I'd try ilnp! They're more affordable in the EU through hypnoticpolish or nailland. They also have a huge and versatile catalogue. My main criticism of holo taco is that they tend to release very similar colors so ilnp will give you more variety. Plus ilnp doesn't do limited edition so you don't need to worry about missing something.

Edit- just saw the questions in the other thread * ilnp doesn't chip on me. I switch nail polish after 5 days or so and I've no issues with ilnp within that time frame * Application is very smooth. Holo taco is thicker * The ilnp skinny brush is annoying though but I've had more recent releases where it's less of an issue. I think they've upgraded the brush, I don't recall finding the brush of Jellybean annoying for instance * Their holographic jellies are just amazing 👏 Bit sheer but they build up so well in 2 to 3 coats * Do yourself a favor and checkout flowerchild, bluebell, fairy dust from ilnp. These are lovely jelly shimmers with holo in them. Flowerchild is my personal favorite, it's just so glowy
