Nice bike that Orbit.
Although I deeply love my bikes (including our Orbit alloy tandem) I wish I owned a steel frame that had been with me for years, much like your Orbit. On Monday night I was admiring that nice Mr Nesbitt's steel Eddy Merckx, he said he'd had it for years.
Decades ago I had a Raleigh steel frame. Only the main tubes were 531 but if I still had it I could have upgraded the forks and it would have made a good bike into something of a classic, nowadays at least.
Moral of the story: think long and hard before you get rid of a bike.
