I know the area quite well having grown up near there, worked near there, and have family who lived there and still do. Edgeley isn't the most affluent part of Stockport and your opinion on it is going to depend upon where you come from and what your expectations are.
To me, having spent most of my life in Stockport, I don't find it too bad and I'd like living so close to the centre of Stockport and having good public transport (Edgeley is well served by buses and you could easily walk into Stockport town centre too). Stockport itself is well served by trains (virtually all of the southbound trains from Manchester stop at Stockport).
Of the areas around you, Adswood has a bit of a reputation (perhaps unfounded) but Cheadle and Bramhall are the posher side of Stockport. If you're not bothered about living specifically in Edgeley that are other parts of Stockport/Tameside where you can still get value for money but a more "villagey" setting, if that appeals to you.
