[Plugin: Alternative Theme Switcher] Update for 3.3.2???

ANyone know of another plug-in which will accomplish the same as this looks like it is supposed to accomplish?

There doesn’t appear to be any plug-ins available for the visitor of a site to select their preferred theme. All the switchers are controlled from the admin. The only one close to what I am looking for is the Theme Switcher. However, it changes the way the Widgets in the admin works and is based on the current theme selected. Seems like a problem to me but the plug-in has a four star rating, so maybe not.

TIA!
