LV_4Runner

My 97 sr5 4wd A/T 105k miles don't have factory rack on the roof. I really don't need rack but I need to carry my ski on the roof. I have been carrying my ski "inside" so far. But having another family member joined this year (new baby!), I don't think I can do that anymore.

Thus, can anyone advise what kind of "affordable" ski carrier for 4runners WITHOUT RACK are avaliable on the market? I need to carry only 2 or so ski's. I do NOT need to carry too much of stuff the roof. Or Do I really need to put factory rack first to put any ski carrier?

Thanks in advance.
