As mentioned by others earlier in this thread, most other cookers take up more space than the original Techimpex. At the time when we needed to change ours, having a grill was important, as also was price, and so we chose the Dometic Starlight which projects above the worktop. Our fold out top originally fitted to go over the top of the old Techimpex stove was also badly scorched (ex charter boat), so it was not important for it to be kept.
The Dometic stove is a little narrower than the original so to make up the space a wooden frame was made to fit within the top of the cooker opening, and then a brushed stainless steel frame was fitted to cover over the wooden frame and onto the existing worktop as shown in the photos below.
The Dometic cooker came with its own set of gimbals which were fitted to the new stainless frame, but I was not entirely happy that the gimbals would retain the stove in place in the event of a knock down while out sailing, so I had two small pieces of stainless tube welded to the tops of the gimbals as seen in the second photo below, and through which I have since placed a long 4mm bolt. The bolt is easily remove able should I need to remove the cooker. As for the gimballing action of the cooker, this is easily handled by the amount of space available on my B36(2002). The cooker has a polished stainless steel oven as well as a glass panel in the door, so it's fairly easy to see what's cooking.
A wooden block was cut, smoothed and stained to take up sufficient space at the bottom front right corner to enable the retaining bolt to engage to prevent gimballing when not actually needed.
