robins are probabaly the sweetest handling planes on the market and have all the benfits of performance/vis etc. I did my 1st 400 hrs on an alpha and it taught me well, I swore I'd never touch a cessna or piper spam can, until I bought one by accident!
cessna's are so cheap to run and easy to maintain, spare parts are a fraction of the cost of Robins and anyone can fix them. This simply has to equate to a better profit margin and less head aches as far as mainteance goes
but you do give up handling, looks, vis, speed and all other areas of performance!
