Many good options in that price range, although some options will need to be gently used. You didn't mention if you wear eyeglasses, some of the options are right at the minimum for eye relief with glasses.
New, I'd recommend the 8x32 Meostar or Kowa Prominar without hesitation. And there are no flies on the Maven B3 8x30 either (far more budget friendly too).
The Swarovski 8x30 CL (my opinion only) is not worth the price they command - unless you want to pay a premium for poor field-of-view. *grins*
Concerning second-hand options - the Swarovski EL (pre-SV), Zeiss FL's and Leica Ultravid in 8x32 should all be right around your budget.
One note concerning the Leica 32mm - if you have deeper eye sockets, fitment might not be the best for you. I had an 8x32 and while it was, IMO, the purest view between it and the EL/FL (had all three), I could not settle in behind it without some shifting around.
Lastly, and kingston eluded to it already, the 7x42 Leica you currently have is not much taller in height than many of the 32/33mm options - lighter, yes, more compact - not by much.
Please consider hanging onto your 7x42 until after you've solidified your 8x32/33 pursuit. BTDT.
