As Pit Viper has said the Megs machine does have a bad record, however i think they did change something to fix the reliability problem.

My own G220 is dying and is just out of warranty, for me i would go with the cheaper Kestrel machine if i was to buy again, gonna see if Megs will do anything with mine first.

Also the Menzera kit is deffinatly the one to go for with either machine.
