New Freezer – Integrated or Built Under?

My freezer has failed and I’m looking to replace it with a new one. The model I have was in built in to the kitchen before I bought the house so I don’t know what style of unit I need to replace it with. The broken model is a Prima LPR150/1.

The freezer sits in a tight gap between two other units in the kitchen, tight up to the work surface on top and with a wooden fitted over the freezer door to match the rest of the kitchen. It sits on 4 legs that rest directly on the kitchen floor.

So, I’ve been looking for a replacement and I’m not sure if I want integrated, built-under, or something else? Could anyone recommend another model that would be a direct replacement for this one?

Ideally I’d like to swap it for something that will last a bit more than the 4 years this one has done, so I don’t mind if it costs a bit more than the average ‘builders freezer’.

TIA,
Thomas
