Product review (4 stars): Nice beer dispenser.  READ other reviews for installation tips.  I did. Here are my tips.
I too was a little skeptical at first, but it all worked out fine.  First off; read, read, read others reviews for installation tips.  I did and it all worked out for the best.  First off, if you're going to go ahead and upgrade to a 5-gal CO2 tank, do it and order at the same time you order your kegorator.  You'll end up saving a few dollars.  I didn't and instead of paying $60 through Amazon, I paid $90 + tax for an empty tank. Here are more recommendations:
1.  The instuctions are a little vague, but try to follow them and the recommendations of others.  There are lots of extra little gaskets and misc. parts that are shipped with your unit.  Don't panic and think you've missed a step.
2.  As recomended, use teflon tape on all fittings.
3.  It doesn't tell you in the manual, but do as others recommende and USE the rubber gasket when you install the beer dispenser tower. I sprayed the gasket with WD-40 first.  It was still a bit of work to twist and lock the tower, but if you omit installing this gasket, you'll lose cold air.
4.  When you first instal your CO2 tank to set your pressure, be sure to turn the regulator valve all the way off, the open the tank valve (just one turn), then open your regulator valve to the required pressue (7-11 psi).  I found it easier to set the preferred pressure at the CO2 valve and when it stabilized, I used the allen wrench to lock the regulator valve at that pressure.  Note:  Be patient when making this adjustment.  Turn it slighly and wait for it to stabilize.
5.  I was one of the unfortunate few who's kegorator did not get cold enough at first. The coldest it got was 40 degrees with it turned to MAX and waiting overnight for it to cool down. I followed the recommendation of others, removed the thermostat housing and thermostat, adjusted the screw a few turns clockwise and reinstalled thermostat. Now the temperature sits at 36 degrees with the thermostat set just a 1/2" before the max setting.

Now for the not so good part.  After all was said and done (e.g. correct temperature and CO2 pressure), I tapped my keg and discovered that I had a faulty beer line.  It had a pin hole at the 90-degree bend of the beer line tail piece.  Beer went everywhere which of course rendered the unit unuseable.  I called the number in the instruction booklet, explainded my issue and they sent a complete beer tower at no cost. BTW, I went ahead a purchased a replacement metal tail piece at a local Home Brew store, cut the plastic tube, inserted the new piece, clamped it down with one of the 'extra' clamps provided and it works fine.  I have an extra beer tower just in case.

I now have ice cold Yuengling Lager on tap.  So, if you follow the recommendation of others, and with a little patience, you shouldn't have many, if any, issues.

Update:  It's been well over a year and my Kegorator is still working like a charm.  Cold, cold beer! Cheers.
