shinbone, I'd suggest you defocus on brand name. All the ones you will belooking at will have supplied a variety of quality grade level guns. Original Quality grade (OQ) for grade and Current Condition level (CC) for level, they will be equal guns. Brand name is not a short cut to knowing the individual gun's quality.
Either postpone buying a gun until you have had sufficient time to learn about British guns or buy from a reputable dealer. Commissioning Toby above to find you a gun would be a very fine approach.
