Mark,
Yes the AA still do a guide.
I know Aldeburgh well. It's a gorgeous place with lots of gorse, heavily bunkered and it is as dry as can be - some say too dry in summer - and you have to be adept at the running approach shot. Many long and tough par 4s, no par 5s. It's not actually a links but it very much plays like one. 2-ball play only at Aldeburgh.
Thorpeness is slightly more inland in feel, again with tons of gorse, though rather more forgiving. I'd certainly recommend Felixstowe Ferry and Woodbridge as partners for Aldeburgh (probably both ahead of Thorpeness), but you'd need to check on whether work has started on the remake of several holes at Felixstowe which must be reshaped to avoid punitive insurance claims from members of the public.
Luffenham Heath is a jewel and well worth visiting. It's very old fashioned and laid back and dogs are still allowed on the course. There are several memorable holes and plenty of variety in them. Unfortunately there are no other worthwhile courses in the immediate vicinity, but it's not far off the A1 if you're travelling north or the A14 if you're travelling towards the Midlands.
The Thetford course is very handsome if you like trees. It's pretty much heathland in character and there is some fine bunkering. It was designed by C.H. Mayo and expanded by Donald Steel. The town was the birthplace of Thomas Paine (Rights of Man, Common Sense, Age of Reason).
There are links to some of these (and mention of many other worthwhile East Anglian courses) in the Browser's Guide in the In My Opinion section of GCA.
