I did similar and bought ELs around 2007. ELs went through servicing this winter by Swaro to fix coating and I paid for new lenses. $250 cost. They look like new glass.I made the big suck in 2004/5 when I coughed up the cash for my swaro ELs. Sucked then but has been a great experience owning them since and never spending or thinking about another set of binos since. I’m sure the update versions are better but I been 100 % satisfied the last 18 years with mine. While my buddies chased every new midrange that promised to be almost as good a swaros for less money.
I may upgrade to a newer version . If I do decide to upgrade I will probably consider used. Or not. LOL.
I bought NLs last year. I’m still undecided if they are better than the ELs. Both sons say No. I’m agreeing so far. I hunted last fall with them. We’ll do more side by side testing on bears this spring. I think the NLs are technically better but looking out the ELs is easier, or more familiar to me. The technical variance isn’t dramatic.
