I recently picked up one of th H&B forge tomahawks, and I purchased one of the cold steel hawks about 6 months ago. Both of these hawks are easily within your price range (under $40 delivered). I compared the cold steel hawk to a Canadian drop forged hawk I've had for a few years, since I didn't have the H&B at the time.
CS: Unlike Cliff's, mine came with the handle fairly tightly fitted. The wood is a light colored and finished rather shiny. The blade has a shiny black paint finish. The factory edge was poor, but a few minutes with a dremel followed by file and stone put a decent edge on it. This is the lightest full size hawk of the three I own. I did some light chopping with it, and it seemed to cut fine, though it doesn't have a lot of oomph. My initial impression was that this particular hawk is configured more as a thrower/fighter than a worker. To test the durability, I placed some wood on a patio paver and on the second cut, intentionally missed the wood, striking the paver with a 3/4 swing. This was to simulate a miss while cutting wood and striking stone. (Cliff's rubbing off on me, I guess

) There was no severe damage to the blade. The resulting ding was easily steeled to say 1mm deep by 3 long and a few minutes with a file totally removed it. Nails hammered with the poll left scratches in the paint, but no dings.
Canadian forged thrower: This hawk is far heavier than the CS hawk. I believe I've seen them at blackpowder events in the $30-40 range. The hawk has a flat black paint finish, and the raised, forged lettering gives it a slightly too modern look for me. Kind of reminds me of a pipe wrench. There is a roughly finished narrow poll that looks almoost like the cutoff of a sprue. The handle is slightly darker and satiny finished, though this may be the result of wear. The heavier weight of this hawk made it work far better than the CS. The impact test results were about the same, but more metal had to be removed to get rid of the ding since the blade is thicker. I struck the poll quite hard with the back of a Barteaux machete and there was no damage.
H&B: Wood appears to be stained with no other finish applied. It could use a good steel wooling when I have the time. Overall the length is similar to the other two hawks I've described, but the weight is closer to the Canadian hawk. The blade is handforged and has what appears to be thin varnish or linseed oil applied to protect the blade from rust. Very traditional looking. Ther is a small burr or ding at the top of the blade that may have occurred during shipping, and some grind marks are visible along the bottom edge of the blade. I haven't had the time to test this one yet, but it balances well and the heavier weight should make it a good worker. If you search the forums, you should find a full review someone did of the H&B hawk a few weeks back.
Hope that helps,
