Jining second-hand projector which is good?

Jining Projector Network: You can publish or inquire about life classification information such as Jining Projector, Jining Projector, Jining Projector Quotation, Jining Projector Quotation, Jining Second-hand Projector and Jining Second-hand Projector for free. Going to the technology market, or the most valuable part of the projector in Yiwei Digital Plaza, one is the original light bulb and the other is the light path. However, with the increase of time, the life of the light bulb will continue to decline, the light path will also accumulate dust, the picture will become dim, and the maintenance cost will be great. Therefore, I personally suggest not to buy a second-hand projection, and now the brand-new one is only about 2 K.
