You can also get a Duna Multy for about £34
I agree that the one you linked is a little on the small side as those are maximum measurements (probably external) and they tend to slope in at the base.
Ruby has given an excellent selection there. There's also this one on Amazon that is a good size (not sure if it's one of Ruby's link but I kept it in my basket on Amazon for future reference). 90 x 40 x 42 but probably more like 75 on the base inside. But it's just under £30 which is why buying something like a Duna Multy might be easier and cheaper in the end, especially if you need to buy the odd tool, mesh and cable ties etc.

Porton Aquatics sell the standard size Duna Multy - not sure if the base is the colour they advertise or not, but you could always put stickers on the base if you don't like the colour
