I admit I have skimmed over the Hornby 66 but if it is less than £120, it will be a Railroad version so older tooling. I believe the Hornby Railroad models no longer have a Ringfield, but it is only 1 bogie which is powered. I am not 100% about this though.
A 66 would usually be too new for me, but occasionally a model comes along which looks so exceptional that I can't resist. Hattons' 66 is such a model.
Having seen pre-production examples, it looks very highly detailed including details like rotating axle boxes, which is an unusual feature of the prototype. Expect all wheel drive on this.
It also has space in the chassis for an 'EM2' speaker as marketed by DC Kits/Legomanbiffo. Fitting these usually involves cutting the chassis so it is nice to see they have thought of it. DCC sound fitted models will be provided with these & an updated project from Legomanbiffo. If DCC sound appeals to you, then the Hattons model will score well on this.
