If the object of the exercise is to go birding (or indeed hunting or whatever) hunt down the best bargain you can get on whichever of the 8x32 or 8x42 Conquest HD you prefer (if you don't know which you prefer, get your ass down to the nearest store that has both, and try them) and start using them right away. Super proven, excellent image and seriously, if you got the newer model or even a SF you're likely to be what - 1% more effective in the field (if that, and possibly less with a SF because you'd be tempted to baby it)?
