I like keeping them separate, because to me they are two different tools for two different purposes. Sometimes I want to have my rangefinder fixed or mounted for stability/precision when I want my binoculars free, or just carry my rangefinder, etc. If you combine the two, my recommendation is don't skimp, otherwise you are getting a Jack of all trades, master of nothing. Historically the more affordable options, you are typically giving up glass quality, and the higher end ones where you pay for the glass you seem to give up the ballistic computer performance. If you would spend $1k on a rangefinder and $1k on a set of binoculars, don't expect a $1200 rangefinder binocular to perform as well as they both did separately. I think their popularity over the last few years has improved the market so you are able to get a good combination of features/performance, but have a realistic idea of your budget and performance expectation going into it.
