I've been using a pair of Swarovski 8.5x42 EL SV for the last few years. Just amazing (arguably the very best) optics, fully waterproof, great build quality, though well expensive. The missus prefers her Swarovski 8x42 SLC HD, they have different optics to the EL SV, but are excellent too and less expensive.
Prior to that I used a pair of cheap Opticron bins for years. Good value for money, nitrogen filled and reasonable optics, but struggled a bit in low light, which is one reason I changed them. The Opticron Natura BGA ED or DBA VHD, which are higher up the range, better optics, build and low light performance than the pair I had. Either would be worth look if I was in the market for something.
