Sorry about your old bike.
I have the Avail 3. Love it. I know people tend to look down their noses at the Sora components, but I haven't had problems with it thus far. The OCR...are we talking OCR W or what? It's the Avail/Defy set of bikes, but before they were rebranded, so you'll be able to get more bike at a lower price (theoretically). Several people have the Avail 1 on here (which comes in at the very top of your price range) and like it.
Same frame, better components. If you get into it, you can upgrade components later, but it's cheaper to get what you want when you buy the bike than to upgrade later.
I know nothing about the others, so I'll leave it to more knowledgeable people to comment.
