Crashed new carbon bike, wanting a new Aluminum frame, don't know witch.

Hello, I previously had a Chinese carbon road bike, with a full 105 groupset. However one day the chain picked up a piece of wire shearing the derailleur off and damaging the seat stays beyond repair.

I have learn't my lesson with Carbon, and are now wanting to get an Aluminum frame. The previous bikes I have ridden and feel comfortable on were about 55cm - 54cm (non compact) medium bikes. I have a budget at the moment from $300 - $700. So which frames would be great?
