Simple hamster cage without wheel ?

i have a hamster cage but i want a silent spinner in it but theres not enough room so i want to get a simple cage with no wheel or a wheel that comes off . I just want to attach that simple cage to the one i have now so i dont really want much in it . Does the critter universe ECO wheel come off ? Cuz if it does ill get that but anywhere you know where i can buy a cheapppppp cage like that ? Thanks (:
