The LBT tester has also been available for many years.  It's the only tester that's directly calibrated in BHN (no conversion scale required).  It's fast to use but will not handle tall bullets or thick ingots.  Although the unit I purchased directly from LBT seems to work fine for the harder alloys typically found in hard-cast bullets, I found that it's inaccurate when measuring pure lead or the softer alloys BPCR shooters use.
The LBT direct price is $100 (You need to Login or Register to view media files and links)

CabinTree offers two tester models.  The Standard Lead Tester is designed for only testing lead hardness.  The Dual Purpose Tester not only measures lead hardness, but also bullet runout, case concentricity, case wall thickness and bullet roundness.  The testers are extremely sturdy, very well made and will handle just about any shape of lead, including standard bullets, thin sheets of lead to much thicker ingots.  Testing is fast and repeatable.  Another big plus is the ability to easily recalibrate the testers should something unforeseen happen such as knocking the unit off the loading bench on to a concrete floor.  Both testers do require a cross-reference chart to obtain the BHN.  I really like the tester and can vouch that Jim Cornaggia is a great guy to buy from.  He continues to support his products after the sale.  
The Standard Lead Tester is $103.  The Dual Purpose Tester is $127.  Check out the testers and Jim’s other products at (You need to Login or Register to view media files and links)

By the way, if price is the overriding factor, you can make your own tester with a single ball bearing in a vice as long as you have access to a flat piece of lead of known hardness.  The known hardness lead is used as a reference.  The lead to be measured must also be flat since the ball bearing is squeezed between it and the reference lead.  The ball bearing indentations are measured and a somewhat simple mathematical calculation is made to determine the hardness.

I also started a similar thread on another forum.  Several persons responded, also with favorable comments on the Lee unit.   

It appears we’ve narrowed it down to either the Lee or CabinTree. Concerning the CabinTree, it was an unfair statement to suggest the calibration would change if it were dropped on the floor. The unit is so stoutly made it’s highly unlikely the calibration would be affected but the dial indicator could get damaged. Over time, if the main spring does change slightly, due to the recalibration ability, it could be easily adjusted back into spec. 

Also, one fellow responded with a link ( (You need to Login or Register to view media files and links)) on the details of the cheap ball bearing method.  If there were ever a question if the Lee or CabinTree was in spec, this would also be a good method to use as a cross check.
