Hi,

The 568.2mm will probably cost you about £150 - £200 more than the basic 568.2.
Basic 568.2 is probably £350 - £450 but you might get one for a bit less if you’re lucky.

If you go for the basic .2 version you won’t need a HD621 but you might find that the mm version holds it’s value better than the basic version.
