While GW Instek is a good brand and their little 1000 scope has better processor and therefore better performance of U/I, it still has only one 1GS/s converter (so same problems as DS1000Z), doesn't have segmented memory, and no decodes.
While you can hack it (they say), for 100€ less you get SDS1104X-E that has two 1GS/s converters, is 100MHz, and decoders included with no hacking needed. It also has FRA if you have a siggen from them. So no, little Instek is nice but not a great deal.
OTOH GW 2000E series are great scopes, but much more expensive..But I would buy them instead of Keysight 1000/2000 series in a heartbeat, on a merit of being better instruments..
