Hi from Far North of NZ

My previous hobby of RC planes has folded (as the nearest airfield is now 3 hours drive) so I need a new method of squandering time and money . Model rail appeals as it is suitable for wet and/or Winter days, but I am not a 'modeller' so will be buying in most of the rolling stock etc. Rather than leaping in with both feet I am researching what I can first, but expert advice is helpful (again the nearest Club is 3 hours + away). A couple of questions (may be wrong sub forum):

- My baseboard space will be 10' x 3' - accessible from long side and one end. I could go a little wider but my arm length doesn't reach 4'. Is this width going to be a major constraint in OO/HO given I was hoping for a double oval +. The alternative is N gauge but would prefer not to.

- My initial idea is to go with a British period setup (to have more fun with the scenery . I will go straight to DCC if possible to save money later. Should I standardise on Hornby or Bachmann - thinking cost, quality, DCC system....? I will be mainly buying from Amazon (Hornby from UK or Bachmann from US). In terms of shipping the US is probably easier. Appreciate this is a personal preference (which I don't have yet).

Any other advice appreciated - I am a blank slate .

Regards
