I know one of those tools is a maxisys by the serial don't know what the other one is.
Only support can verify that but I haven't seen them in a while. Regardless be carefull
who you buy it from, make sure its the original owner of the tool and that you are able
to tranfer this tool under your name. To verify if is under an update period just connect
it to the internet and try to update it and you will know. Regarding whether it will be a
good deal or not it depends on the sale price versus update fee. A 905 sells for about
1500 dollars,1900 for the 908 and about 2500 for the 908p with a one year warranty
and update. The update fee ranges from 800 to 1200 . Keep that in mind when making
the deal it may or may not be worthed . Good luck. Note I have never seen a clone
maxisys .
