In reply to thebigdon: I've lived in Lower Stratton (on the Oxford side of Swindon)since I moved here in '79. Handy enough for everything without being in the middle, but then Swindon isn't that big anyway.
Depends on what you want really; young and looking for nightlife, older with kids and looking for good schools?
My kids were reasonably happy living here 'til they moved away for their jobs.
Really there's only a couple of places I'd try to avoid living in. Any of the outlying places (Wroughton, Wootton Bassett, Highworth) are worth a look if you want a villagy sort of place.
Happy to offer an opinion about anywhere if you want to drop me a line.
