I rent a house with the above projector installed. Have been using it for 18 months, but now the lamp needs replacing at a cost of $396 for genuine. Am wondering if it is worth replacing, considering the projector is now 8-9 years old? I don't want to fork out that amount of money if the projector is going to fail due to age anyway. Could go out and purchase a brand new big screen t.v. 55" for only around $800. Any assistance appreciated.
