Hello Pat,
Just a few lines to say Thank You.
I purchased the 44 and 35 plain base dies over 2 years ago.  I have made thousands of checks. Your dies have performed flawlessly.
To tell the truth,  I worked the Heck out of them. 
There are many shooters who appreciate your devotion and commitment.
Again Thanks.
-John Leone
I have one of Patmarlin's 35cal PB check makers.
I get my aluminum from soda cans.
The die is ingenious, works beautifully and so do the checks.
