Wana good performance/price look for Rigol or Siglent, Both are the chineses ones with at least some engineering Inside
Special attention to DS1054 and MSO5074 both are the best ones on their price range ( 350 USD and 999), I have both and I'm happy, avoid craps like Owon, and Hantek, is all 2nd class products
Of course, the tektronics and Keisyghts, are a little better specially on firmware, but never justify to be 6 to 8 times more expensive for the similar ones From Rigol or Siglent
