Best DVD Release?

Just acquired one from Direct Source (Canada) & the picture looks very blurry. So, then I check Amazon to find that there's also releases from Trinity Entertainment (the default cover on the main page), one from CineVu (may be OOP) & two from VCI Entertainment. One the film, alone & the other, a double-feature w/ The Efficiency Expert. Of the latter three, which would be the best to get (assuming that both VCI releases used the same master)?
