What's next?
If you haven't already started upgrading you may soon have few options left other than to buy a new TV. If this decision you make I recommend you be aware of what technology is that you are buying. Don't just get what looks good, plan to buy the most current technology in display and signal capabilities but don't just get the nicest you can find.
While this sounds like you will be spending allot of money think again. There has been a large influx of new models to choose from which has subsequently caused prices to drop. Unless you are trying to buy the largest size LCD flat panel a very reasonable display for under $1000 dollars is possible to find. This amount may still be too high for some so there is yet another option becoming more available. The secondary or used market is becoming more populated with HDTVs and converter boxes from people that did the upgrade as a temporary fix. Checking local Craigslist listings you will find a handful of flat panel sets.
If you can wait until Thanksgiving, the week of black Friday will have some unbelievable deals that will give you allot more for less money. But remember the TV you buy today will be obsolete in less than 5 years. this doesn't mean that you can't use it after 5 years it is just not going to be as nice or have features that make it more enjoyable. The next step in technology will be available soon. Look for wireless whole house broadcasting so you can watch TV from any room without running wires. This is just a few years away and will make your DTV source easier to connect where ever your TV is. The intent is to make TV broadcasts more mobile not just to reduce the wires needed in the house.
