Boat out today mainly to remove anode - found it only to have slight pitting, its be on two years, is that OK ?

How much has the anode wasted from new ? if it's not lost much weight and has a few bits that have eaten away just buff it up with a bit of sand paper / emery and leave it. as long as it's not loose and free to rotate it should be okay for another season.
I normally make a habit of weighting my anodes. but do bare in mind if the anode has started to erode the surface area will be greater so in theory will erode at a quicker rate the next season.
saildrive ring anodes are about £20.

Lucky you - sounds fine to me, no need to change.
I assume you are talking about the prop anode. If it's a Yanmar bear in mind you probably also have a pencil anode at the top of the drive inside the boat, opposite the Kingston cock. In my experience these degrade more slowly, but need checking.

Betamarine quoted me £78 (!!) for a new ring anode. Anyone know of a cheaper alternative?

Generally reckon to replace at 50% weight loss. Rough edges etc are normal in my experience. Clean the old anode with brush/vinegar.
I always have a new one to hand in case waste has suddenly accelerated - it can hapen. Hunting round will get discounts: check out with Keypart of Kings Langley - they deliver post free at the moment. (no personal connection)

Volvo are about 50% of that believe it or not.

I find that the anode on my Volvo 120S saildrive lasts several years. The three-part ring anode on my folding propeller, however, barely lasts a season.

You'd expect the anode on the leg to last a reasonable time, unless there was some problem causing excessive wastage but you'd expect the anode fixed directly to a copper alloy prop to disappear fairly quickly.
