Lots of good bows...if you are really interested in shooting trad, just buy a bow, used... and shoot it....if you dont like it, sell it and buy another... keep trying.
Looking at the used bow classifieds like listed above, you can find thousand dollar customs for $400.... just be patient....
If you are looking for a 30" draw bow, just add about 6# to any bow marked 28.... Now...some bows are not designed to draw 30, but MOST you will be fine!
Good Luck, keep us posted!
