I got my first suite from Burtons. Cost about £100 for blazer and pants. Been great and looks smart. You don't need to spend hundreds at all on your suite. Just make sure it fits well and could be worn for a variety of occasions - ie don't buy a colour that you know you'd only wear to a party and not a formal occasion. All suites are hardly 'confortable' to wear for long periods, so I don't think spending thousands will get you anymore than bragging rights and maybe a slightly better fit.
