Personally,
I would only do this if it where a target only proposition. Even then I would get a better one, like a Aim-point. (read expensive)
Like trotterlg already mentioned, cheaper ones really have parallax problems and their batteries never last in the cold temps we usually hunt in. They are not bad at all in the warm.
I shoot bulls-eye competition and use both open and red dot scopes. I have had some good luck with ULTRA DOT brand scopes. these are about half what a Aim-point will cost you. I have also not had the parallax problems with them. But I am shooting them at only shooting them at 25 and 50 yrds. My main and first choice is the Aim-point.
