I prefer the non-mainstream bikes and Curtis, from the little I know, make nice frames. Different too, in so far as they are not a name I often see when out and about. I quite like the colour too.
For me, as you're asking, I just get a feeling that yours is trying a bit too hard to be different in a purist, niche-y kinda way. And at £1000, a sense of it being a bit too contrived. Maybe that's where the parts bin comments are coming from?
So, despite your rather alluring and possibly self-proclaiming monika and irrespective of what you feel is a 'killer deal', listen to the market and the many positive comments above, split it.
