    Having spent several months trying to decide which plasma to buy, I am now coming round to the idea that I would be better off buying a RPTV at 2.500 euros and replacing it in 5 years' time - rather than find myself landed with an aging plasma that had cost me 7.000 euros.

    Two questions come to mind:

    1. Should I wait for more DLP models to appear? Can we expect them to provide a significantly better picture?

    2. Do the lamps of a traditional RPTV need replacing and if so how often and at what cost (approx.)? I would not want to have to pay 20% of the cost price of a RPTV to replace lamps every year or two.

    On the basis of what I have read on this forum I gather that the Toshiba xx WH 36 models are particularly recommended.

    Thanks in advance for your comments and any further advice!

    1) You might see DLP rainbows, if you do it'll give you headaches, make you naushous etc.

    2) CRT RP's use three Cathode Ray Tubes (Red, Green, Blue) if treated well (turn contrast to 50%) probably last 10 years or more..cost of replacement is about £700-£1000 for the set. But by that time you'll probably be looking at another RP/Projection anyway. Here's a picture inside a CRT RP (my set)

    LCD RP's (and projectors) use a bulb- which costs from £150 to £400. These last anywhere between 2000-5000 hours. Also the LCD panels could suffer from heat soak (the heat from the bulb damages the panels) And due to having a fan- LCD projectors get more blocked up with dust; compared to CRT RP's.

    Here's a snapshot of from Shrek. Actual image is much better- even brightness, much more detail & focus (hair, skin & eyes detail is visible)
