Most of the planes suggested so far are quite tricky to buy in the UK, and i know that the Zen series are very highly priced.
The Mk 3D dancer i saw flew very well, but again around £310 from probuild.
The capiche 50 is the best plane i own, and flies 3d and pattern very well for a 50 size plane. In my opinion it has a better feel going from 3d to pattern and vice versa than the 2m ZNline Majestic which i had a go on the other day.
The capiche comes in around 5lbs with a Saito 72 or YS 63, and a good deal lighter with the West 36.
Think its around 58 inch span.
Here are some pics of mine.
