I prefer a round pell only because you're able to rotate it indefinitely and not cutting directly to the flat edge of thw timber.

I'm relatively new to HEMA, but here's what I made: I actually found a tutorial for a hanging pell a while back that was relatively inexpensive and works well if you have a place to hang it. It was basically a length of rope knotted near the end with a dog Kong toy (or off brand version) slipped through such that it caught on the knot. You can also create a small loop at the end of the rope that hangs from the bottom of the Kong for thrusting practice. Of course it kind of looks like a noose. You throw the rope over a tree branch of something, adjust the height as needed, loosely tie off the non-Kong end (e.g. wrap around the tree trunk), and you're good to go
Pros: Inexpensive, can change height easily, no base that you may trip on Cons: Swings when hit (may be a con), smaller target less like a person standing there, requires something to hang from
