Need ideas/tips for buying maternity belt

Hi Ladies,

Am 30 weeks and 4 days pregnant and having more pressure downwards (due to baby's head being down now). Dr suggested me to try craddle now. But, I dont know if craddle is comfortable or normal ab belts.

Need some ideas/tips before i buy one.
Anyone using belts now to reduce ab pressure? Please let me know.

Below are the 2 I saw online: (1st one suggested by dr, 2nd one I feel i will be comfortable):

It's You Babe Prenatal Cradle: Home Health Care : Walmart.com

i dont know how to wear this craddle 24/7... instead, i liked one simple pregnancy belt just for lower abs..

i liked the below one:
