Analog MSD repair options? ....

Was reading another post,about digital MSD boxes reliability. Did a Google,got this website:
http://www.techwestracing.com/... (I don't know anything about them,just read a post from classracer.com). I know of at least a dozen boxes ,that need some T.L.C......Any leads/knowledge/idea's? Please share,any info good or bad. Thanks..

I just posted about my issues in the forum started here on FABO about buying one .I'm down to trying the polarity swap trick before demanding a return code , I bought on impulse because of the new dial rev limiter setup and regret it , I will be going with TrailBeasts HEI setup after I get sell mine , I think he may have figured out a rev limiter setup for it as well but don 't quote me .
