I realise that this is obviously a question you may not be able to answer for a number of reasons, but out of the 'branded' units/brands that would usually be considered safe bets by many, are there any you would actually advise to avoid right now?
My recommendations are in the OP, those are what I would personally buy. That is all I am saying on the subject, if it is not in the OP I'd not buy it for me personally.
