Masterclub are good, as are the ModelKasten tracks.
Just happens that I have a couple of sets of the Friuli T-55 tracks here to use.
As far as the KingTiger's go.....while yes the Meng KT will be cheaper, it also doesn't come with an interior like the Takom one does.
While there will be an interior available, it will be a separate purchase, as will the workable tracks, and the zimmerit. So to replicate what comes in the Takom kit with the Meng kit....likely going to cost you more.
Of course if you don't care about the interior, workable tracks and zimm....then by all means, yes it will be less expensive kit.
