Not knowing where you live or how far you plan to shoot, I'd suggest getting the binoculars first...
They will help you see and evaluate deer before they get close enough for a shot and can also help you see deer that don't come in so you can reposition your stand next time...I use the Nikon 8x42
Monarchs...I think they run around $300 or so...
I never had a problem not having a range finder because I practice judging distances and then pace it off to see how far an object is...On stands that I frequently hunt, I mark trees with a slash, one slash is 10 yards, two is 20, etc...This gives you a point of reference once you climb into your stand...
I did buy a Nikon range finder about 3 years ago and have enjoyed using it, but I bowhunted for 40 years or so without one...
You'll probably end up with both sooner or later...
