Thermo cat cup or hut?

I am looking to purchase a thermo cat hut or cup for my two kittens. They are quite pricey so I am wondering which one is best. I saw a few on ebay that have a hood that can be put up or down. I also saw the heated cubes and heated round beds. Anyone out there have any of these? If so what are the positives and negatives with each kind. I don't mind spending the cash if my cats will enjoy it. Right now they only have a cat climber that has a house on it with high towers. I never see them inside of the house but often see them on the towers. There fav place to sleep is on my computer desk, chair and my small bathroom floor that has a fuzzy rug in it. The bathroom is always very warm as it is small and the heater is such that it blows warm heat across the floor.
Thanks for any suggestions!

It's a tough call. My Molly used to love cat beds that were cups or anything like that. Abby is very distrustful of them and only likes mats. She doesn't like to be enclosed. I've bought her some heated mats and she loves them.

Same as Karen, it all depends on the cat. Some of mine like their beds, others prefer my sofa

I have a heated round bed and a heated furry long soft bed mat that I stuff in an enclosed cat bed for extra warmth. Both are used everyday all year around by my Sphynx.
