While it is true that you do not get the image quality of a good binocular with a combo, the convenience of carrying one item instead of two can trump the optical quality consideration.
Now, if you DO get two separate ones:
-The range-finder does NOT need to be expensive, in my opinion. Just try them out in the stores to make sure they are user friendly and work - you can zap different items throughout the store. There is VERY little difference in the supposed 400 vs 800 vs. 1500 yard ones. They all work basically with the same effectiveness at the same ranges. They're good for about 200 yards for most items, but for a large reflective item like a big rock then maybe 400-600 yards. I wouldn't spend more than $150 or $175 on a range finder - just get the Bushnell Yardage Pro 400 or similar and be done with it - they work great.
On binocs, it DOES pay to pay more - you will cherish and appreciate as rcmodel points out, a high quality optic for many decades to come, or to pass along to kids.
But that doesn't necessarily make the combos bad ideas. You may not need high-quality optics as much as you need the benefit of "gadget consolidation" on certain hunt scenarios (long walk, where both are useful, and weight savings needed).
Range finders are not really needed for the hunting *I* do with RIFLES. But they are definitely helpful for archery. I get in my stand or blind. Then I pre-range all sorts of different spots where an animal could walk through, so I know whether any given open spot around me is closer to 10, 20, 30, or 40 yards. Sometimes what looks like 30 can be 10 or 15, and vice versa, to the naked eye. Gotta know which pin to use. Very useful. Out west, in dryer climes where you can see a long ways, range finders are also useful - once you shoot at something past 200 or 250, you have to know your drop, so you have to know the approx. range.
I almost got the Bushnell combo deal once, but it was the large size that turned me off. I still plan to get the Leupold combo unit, once they combine the ARC technology of their other rangefinders into the combo unit. As mentioned, rangefinders are MOST useful for archery. And since most archery hunting is done from a tree stand, at a steep angle, the ARC features are the most useful for archery tree stand hunters, espec. since the angle is steeper due to the shorter range.
And lookit, Leupold is not going to put out any item that has crap optical quality, so my guess would be that this is a gem of a little item to own, if you can swing it:

Anyone have a link to a review of this product?
Edit: Hey, whaddya know - the Loopys DO now have the True Ballistic Range (ARC) thing incorporated into their combo unit! Wow, that is precisely what I've been waiting for for a couple years. So the RXB-IV is now immediately going on the "to be acquired" list, bigtime! Thanks for bringing it up!
I just wish it was 6 or 7 power, instead of 9 - that's a little on the high side - but it doesn't make a great deal of difference.
All a game camera *might* do is let you see a night pic of that HUGE buck which you will never see in the daytime. It's kinda like going to a strip club and not being allowed to touch (or so I hear) - nothing but frustration.
