I also like the Rhinoblock XL. Very durable and can take a lot of broadheads. They're so dense that when they're new, you'll need to lube your arrows to pull them out. It gets easier once it's gotten broken in.
Another extremely durable one is Morrell Vital Signs Combo. I'm still shooting my Morrell after 5 years, without complete pass-thoughs. The newer Morrell models are bigger and crossbow speed rated, but they're $250-ish. Both options are expensive but worth it, considering you won't need to replace them for years. A lot of people like the Blob targets, for durability, but they're not nearly as portable.
For budget broadhead targets, I like Block Classics. I like the 22" model for up to 80 yard shots. If you hit the same spot a few times, though, arrows start passing through. I can get about 1 year out of one, if I start adding my own spots in the unshot places, with duct tape X's. Still, they're very portable. I have to go to public land to practice out to 80 yard shots. My backyard maximum range is 40.
