This isn't a commuting question, but I'm hoping someone here or in Touring may be able to help.

I have a Breezer Villager step through frame bike set up with two child seats--a iBert front seat and a Topeak back seat. If I put on a backpack it would be right in my daughter's face. I can't put panniers on the back because of the rear seat and the iBert takes up the space I could use for a handlebar bag, so I'm looking for a way to transport stuff. I've been looking at lowrider or low profile front racks, but I'm not sure what panniers would fit. Most of the touring panniers that look like they would fit are super expensive. I'm looking for a sub $50 solution if possible.

Any thoughts?
