Thre Parker line of bows are a fine line as are 99% of the bows out there today.Some are better than others but all,for the most part are good.
As long as the bow fits you and you are comfortable with it you should be fine.There is no rule that says you have to spend $700.00 to have a good setup.As a matter of fact,I can't understand why so many think they need to spend that much to shoot deer.
Good luck with your new bow.
