For EWS systems (E36, E39, E46, E53, E85, E38) I use AK90. For MCU mask 2L86D (EWS4.x) if you do not want to solder, there is a solderless adaptor from UK which can be used with Xprog-M.
For CAS the best way today I believe is the BMW Multi tool. I already also have a clone of BMW Explorer, but the software version is old and it is only good for making keys on CAS which has not been updated. Downgrading CAS is not a good way to go.
