All this excitement about the WEST COAST based multiple units, whilst those of us on the east don't have anything RTR, and there are a lot more options available:-
313 / 314 / 315, 317 / 318, 319 (a large class both north and south of the Thames) 320 / 321 / 322, and the 365's
So Hornby, Bachmann, Heljan, Dapol - and all you commisioning retailers, five possibilities for you.
And you also have the newer classes like the 333's and the Heathrow sets.
