first off, what is the primary tip you plan to be shooting most of the time. are you looking for a field target or a broadhead target?
how much are you looking to invest.
for box type broad head targets, the multilayer targets get some reasonable life. mine lasted about 4 years and initially cost me about 65.00. I have heard that the t-rex brand of targets are good as well but have no personal experiance with them. for field targets I like the morrel multi dot target that goes for about 100.00.
