Ignoring the price, I did consider that 2.5kpts is probably ok for basic and amateur users but the aliasing issues are a massive problem and thoroughly resolved in every other major brand scope. I can see new end users tripping over this without an understanding of what is going on.
But including the price, at £1170 for a 100MHz unit (TBS1102B), it's laughable. That's 3.25x the price of a 4 channel DS1054Z or 200MHz SDS1202X-E.
Tektronix can get fucked.
