Non turbo Arrow-Not enough performance for the extra money
The Robin DR400-180 will do almost what the PA28R will do but without the expence of retracting gear and CS prop.
To me that makes the PA28R too much expence for too little extra performance, if a PA28R is what you want get one with the Continental TSIO-360 engine, at least with the turbo the performance gap between the DR400 and the PA28R starts to make some sort of sence in terms of cost vs performance.
