Dear Mitchell,
I own a Roundhouse Lady Anne, Accucraft Ruby (actually a friend gave me this, very kind and it's a sweet little engine) and a Sabre Steam Annabel amongst other things.
I run them all, each has it's appeal and I wouldn't be without any of 'em. Operating a coal fired locomotive has such a romance and appeal though, something those who don't own or operate a coal fired loco may not appreciate. My Lady Anne is fully radio controlled, including the whistle, something my Annabel has no room for, everything, including its whistle is manual. But then its such a hands on machine, it doesn't really matter.
As far as operating my Annabel, it is a complete joy, every run is a little different. Maintenance comes down to regular cleaning, its much more intensive than say the Lady Anne. But, strangely I enjoy the process and I am so well acquainted with this loco because of it. Aside from that, it requires no more maintenance than any other good quality loco.
So, is it worthwhile going for the Sabre Steam, its a simple decision really (cost aside). If the challenge of firing your own little dragon and the sense of satisfaction that that provides, and the thought of your coat smelling of burnt coal whilst sipping a beverage excites you (as it does me), then there you have it.
If on the other hand, you really prefer to plonk yourself down on yer seat and sit quietly whilst your pride and joy chuffs past your nose, then gas is ideal.
Me, I love both and am fortunate to be able to experience either.
