I had a Rex (Mycroft) and he didn't need any extra care coat wise. However both myself and my husband turned out to be allergic to him due to his coat. Luckily I was only mildly effected so cuddles and grooming were still possible, however my husband had a serious asthma attack if he held him etc.
We had intended to keep him and his half brother at indoor pigs, but we had to house them outside when we twigged what was making my OH so ill. So a word of caution - double check you're ok with this coat type if you have allergies and intend to keep them as house pets.
