Is there much difference between a generic power supply costing less
than $20 to those costing over $50 ? I have an old vtx400 gateway that
I bought second hand for $200 and lost the power supply. Any low cost
brands that are recommended?

Thanks,
Chris

There might be and there might not be. All judgments cannot be made
solely on price.

If this is for a laptop (one would presume that, since this is the
laptop group), if it's a 2-wire coaxial connector, any power supply
producing the right voltage and enough current will usually be fine. If
the power supply interface is more than 2-wire, then you probably need
an OEM supply (one made by the laptop mfgr).

Used power supplies on E-Bay are very reasonable.

*** Speaking generally, the cheaper ones are more likely to have
just-spec'd, or even under-spec'd, components. The other side of that is
that the manufacturers' ones will be more likely to have some charge for
the name included.

*** I would look for a used manufacturer's unit. Barring that, go for a
mid-priced one with the same voltage, connector and polarity, and the
same, or higher, current rating.
