Steamers continuous fill?

[Mike@ShineStruck]

Are continuous fill versions of the same steamer worth the extra 200?
Anyone with a single boiler system, do you ever really need to refill?
If you do, how long for it to cool down to refill? Plus the nkrm time to reheat too?

It's worth the extra 200.00 I've taken on big cleaning projects other than cars.
