I recently got a good deal on a McKenzie shotblocker, bowhunter sized target. No problems with broadheads or fieldtips. I like the McKenzie it is not a straped target or the material isn't compressed into a wooden frame. Thats just me. They all work about the same I'm sure.
I also use a couple very old Delta (I believe), 3-d buck targets. One has been in use for over 15 years and I occasionally just refill the shot out area with canned foam and give it a quick touch up with Light brown paint. Looks new from a distance and it still functions great, I would recomend that type style any day. My other 3-d target only has about 12 shots into it, its also about 15 years old and sits in the basement waiting for me to get rid of the other. They stop both field tips and broadheads as advertised.
If your handy with a few tools, have some old sheets or clothes you don't need and can get the milk crates to use for a frame, as well as a few other very inexpensive items, build one.
Here are the pictures of the one I built last year, I don't leave it out in the weather, the interior clothing material would surely get ruined by mold, and you can't use broadheads in it but it is an awesome target for field tips and they pull out much easier than any other target I've used.
