Which 1210 to go for?

[aniki]

the lid is held in place with magnets

Nope. No magnets (Aluminium chassis). The later lids are just placed on the deck and sit on rubber buffers.

That's what my one has

[allthingsanalogue]

MK5 - greater range of anti-stake adjustment compared to the mk2 and the lid is held in place with magnets
M5G - special edition with high gloss finish with metal flakes, special digital pitch slider than can switch between 8% and 16% range, fancy blue cue light, hinged lid, tonearm has a fancy finish and OFC wiring and the body has improved damping
MK6 - is basically the M5G without the fancy finished plinth, arm or the fancy pitch slider but keeps the OFC wiring and damping improvements.

My MK5G I had didn't have a hinged lid or magnets. It just sat there.
