Belly bands and maternity pillows--what am I looking for?

I'm only 17 weeks, but I'm finding things like sleeping and bending over are getting more difficult as this bump starts to show itself! My doctor recommended getting a belly band. I looked on Amazon and there are various kinds. What am I looking for in a belly band? Are the cheaper ones that come in packs of 2 and 3 fine? Or did you pay more? One is even mesh/breathable, which is something I hadn't even considered would be necessary. Any advice you ladies have in this department would be really useful!

Same goes for maternity pillows. Did you find them useful? Are there specific things I should look for in a maternity pillow? As I said I'm still only 17 weeks so I have a lot of growing to do still!

Thanks in advance!
