Depends on how much you would like to spend fella, quaife box is 3k plus the vodka and tonic, not sure on prices on the barra units, swedish fixit kit is good but its hard to get your hands on spares,
Personally I'm going to go for one of the oppliger boxes off Romain in Italy

1700 quid and a little bit more to then fit the gearkit into my casing

happy days
