Unfortunately, exchange and duty make it not worthwhile for me, but vgoodiez has a very good reputation and are very active and responsive on reddit. Good to hear you've also had good experiences; I trust opinions here much more than on the big sites.
I pop over to reddit on a rare occasion, mostly just to check out some grow pics. Usually after the first post or two I've had enough and bounce, not a good place too many bad apples, spoils the whole bunch for me.
I would wholeheartedly recommend you send at least one of them in for the upgrade. Or do the upgrade yourself if you feel up to it, the instructions are out there.I have 2 of the original VB's (VB 1.0 ?) and still use them
