Any recommendations for a maternity support belt?

I'm currently 17 weeks and just finally starting to feel somewhat normal again and not sick all the time. I have been having a lot of pubic symphysis pain and my doctor has mentioned the possibility of getting a maternity support belt to help take some of the weight off that area (baby is sitting very low). Does anyone have any recommendations of one that is comfortable and not crazy expensive? I'm a bit concerned about being able to wear one because so far I can't stand anything tight on my belly so any advice would be appreciated!
