Turnstiles - What Is Your Preferred Manufacture/Brand?

Hi All, I usually install Alvarado just because it has provided good results and the ones installed have been there for many years without problems.
However, I understand there are multiple manufactures and type of turnstiles hence I would appreciate some comments/feedback based on your professional and personal experience:
<ul>
<li>Preferred Brand/Manufacture?</li>
<li>Global/Regional distribution?</li>
<li>Installation?</li>
<li>Warranty?</li>
<li>Pricing?</li>
</ul>
Last but not least, are you familiar with Syscom's turnstiles? Are they good/bad?, how do they compare with other brands such as Alvarado?
Appreciate your comments
