What model of Miyata is this bike?

I found this bike for sale online in New Jersey USA for 125 dollars? It's aluminum frame, I believe it's a Miyata 1000a 1989 bike but I'm not sure. Can anyone help identify this bike? Also is it worth it at this price looking for a bike to commute with in urban area on a budget of 200 Thanks!

If $200 is your budget for something that is going to be 100% reliable and not kill you/have to replace parts/take up loads of time maybe grab a single speeder from somewhere?
