As already noted, to get a grill all the cookers are too high to fit under the cover. When I replaced mine I fitted a Pacific 2500 which is the same as the Neptune but without the grill. Does not bother me as I find grills messy for cooking and toast using one of the patent toasters on the hob is fine (but not a great toast fan). Cooker is fine, but if I had gone for the higher ones I would have fitted a Nelson Spinflo which seems to me a bit better made, but they don't do it without the grill.
Whatever you buy will be better than the Techimpex.
