New Tek 2000B? Can you point out a specific model?
The TDS2000B (ie, TDS2022B) was discontinued some time ago.
If you're talking about the TPS2024B, then there's no reason at all to buy that, unless you really want the isolated channels (maybe the battery).
If you're talking about the DSO/MSO2024B, then there's no reason to buy that, because you should be buying an Agilent MSOX2024A which is on
eBay for $2421. Probably less if you bargain Oliver down a bit.
