If you have good working relationship with Best Buy, you would have 30 days to figure out if model works for you. And if not , return it.
No matter what model you get, there will always be a better PJ you could get for more money. Same thing if you bought a hdtv. There are always better ones coming out.
Look at user reviews on Amazon going from newest going back on any model you are thinking of getting, so you see what people are saying that have just bought it or had it the longest. Look in forum rooms.
Go to Projectorreviews.com and read Art Felerman's reviews of the models you are interested in. And the 2011, 2012 roundup. Then give it your best shot.
Not sure why the other guy is recommending a hc3800 refurb from a certain company and he is not giving the price or reason you should get it. Does he work for that company. Can't he say more that just a one line statement, like why he thinks it's the best. How is one year warranty better than 3 years.
I have owned my pro8200 for 9 months, and I still have 2 years and 3 months left on my warranty. If I had one year warranty, I would only have 3 months left and if it broke in 4 months, I would be screwed. You were thinking of the costco because it would give you longer time to return, but 3 years warranty gives you model you don't have to worry about for 3 years. Read what amazon users think of that optoma 180 too.
Now your sony sdrd 60 was 3,999 dollars when you bought it , right? Rear Projector TV. So, 799 for pro8200 is a hell of a lot cheaper than 3,999. You might have high quality tastes, so maybe a 4,000 PJ might be good for you. I don't know.
So doing the Best Buy option, will help you put your toes in the water to see if the pro8200 works for you. If not, get a 4,000 dollar PJ .
The pro8200 has a usb port in the back for service, but I use the usb port for my usb speakers , the type you use in computers and use the audio plug in back of pro8200 for extra sound, WORKS for me. The 20 watt speakers are good in some settings, but may not be loud enough in big room, so either use sound system or bring usb powered speakers with you for compact portable use.
I was at buddies house, and his roommate said the sound was too loud when I used the 20 watt built in speakers, and his roommate was in the back room in his house, many rooms away. So it depends on room you are in , and if you NEED extra bass, you can add subwoofer in audio out.
