also consider the TWM levers, I have them on my bikes and i understand they are made by the same manufacturer as the DP version, but at a different price point. I bought my last ones from- https://www.bikersdiscountstore.co.uk/brake-clutch-parts-replacement-brake-clutch-levers-pl-135.php
What Nath said… think I paid about £140 for the TWM long / folding levers and the only difference is the logos.
