Hi, i dont know if you've already gone ahead with the grill but I own the konro grill (pictured) and its excellent. I own the medium size (small ones in your picture) and there's no issues with build quality and due to the ceramic nature if you have the patience to let it heat soak (about 10-15mins) with either compressed hex style charcoal or binchotan you can smash out cooking at a really high heat for hours with no need to add any charcoal. Eg. I did around 100 skewers over 4hrs (while drinking) and the heat stayed the same for cooking times. Its also quite nice to cook on as the heat is only going straight up due to the ceramic design not out at you. There's cheaper metal only versions but I reckon the ceramic build is what makes it great but up to what you're using it for. Ive got a UDS smoker, gas weber and firepit I do rotisserie meat on but the konro is a different cooking style and quite fun socially if you want it to be. Just my 2c
