Some info on my side of Manchester. Salford in particular is currently undergoing a lot of urban renewal, so lots of new apartments going up that are not too expensive based on two people holding down jobs (600 hundred a month would get you a pretty trendy two bed apartment in a nice development close to Manchester city centre. Salford is a fine city with tons of history and borders central Manchester so it is very easy to commute in and out.
However, be aware that Salford is in the early stages of urban renewal and can be a dangerous city to live in. The crime rate is high and a lot of the new developments are in inner city areas where one must be alert. Myself and my USC wife lived in Salford in 06 though and she loved every bit of it. We would walk past churches that I had seen a thousand times and never even looked at, only for her to discover they were 8 and 900 years old. So, it has it's problems but I wouldn't let that put you off. It is still much cheaper to rent there than in South Manchester. Choice areas (South Manc) are definitely Chorlton, Withington, Fallowfield etc, but very expensive and at risk of crime. The reason being that a lot of these areas are very studenty and students are seen as easy rich pickings to the criminal fraternity. Moss Side and Lonsight are very close by and they have a bad reputation for gangs and guns that are a lot more like American style gangs than in other parts of the city - google The Gooch. Doddington, Longsight Crew and Pit Bull Crew to get a better idea;
I would not even venture into areas like Cheetham Hill. Whalley Range, though again a very studenty area, are is far too close to 'the moss'. As is Hume, though Hulme is redeveloping fast. Still, the general concensus in these areas is that urban renewal ends when the sun goes down so be aware.
At the end of the day all areas have their problems and you can avoid them by being sensible and aware that you are in a big city with a large population. I personally love Manchester and love Salford more. If you can afford to live on Salford Quays go for that. Or, further out Worsley is gorgeous (along with Monton) and much quieter crime wise. These areas have a good mixed population of 'locals' and post grad professionals and the atmosphere is great. We lived in an area called Ellesmere Park which is in Salford but not quite central and so, again, a lot quieter.
Wherever you decide, Manchester or Salford, you are going to love it and have a great time. If you google flats in Salford and North manchester - feel free to PM me and I will tell exactly what the areas are like. Good luck and hope you make it over soon
