You have limited choice here from Flymo. There is really no alternative to for the Venturer mower. The box is a wee bit expensive for what it is, as are many Flymo parts. Considering new mowers are no so much cheaper I think the parts price should be too. The box is a bit flimsy and the holes/vents are a little too big - serving some purpose I guess but we will see if it stands the test of my garden!!
