Best scopes for the money in ascending cost:
Leupold VX3 2.5-8x36 plex
Swarovski Z3 3-9x36 plex
Swarovski Z3 3.5-10 BRH
Leupold Z5 3-15x44 firedot CDS
Swarovski Z6 EE 1-6x24 (discontinued)
I really don’t see any reason to go less expensive than the VX3 2.5-8x36. It is priced way below its quality.
One cautionary note; there were some very good Zeiss conquest 3-9 scopes made. However, something happened at Zeiss with this line and a bunch of crap scopes were sold. If you’ve got a good one (I do) great, hang onto it. However, I wouldn’t buy a new or used one with someone else’s money.
The early conquests and by early, I mean olden times mid 2000s, the glass came from Zeiss Jena and somewhere in the southern US they were assembled and had a full tech department. I know this because I sent one back for a reticle change in maybe Georgia? They were wonderful. Outside of box was silver or white with blue zeiss logos. Inside was white corregated cardboard rolled around the scopes.
Fast forward and the conquests became Japanese at the same pricepoint. Basically, they were Nikon Monarch quality for 2x the price.
You want the original, not the latter.
