Dear Aleksandra, we have a Tecan Sunrise plate reader (http://www.tecan.com/platform/apps/product/index.asp?MenuID=1260&ID=682&Menu=1&Item=21.2.10.4). The support is quite well.
I don't know the price (maybe it's different in different countries?) but maybe I can tell you the price tomorrow.
8 channel, dual wavelength detection (one for you substrate, the second one for optical errors), wavelength according to your substartes (TMB in HRP = 492 nm, ...)
Connection to PC, the calculation of calibration curves and samples ist much mor comfortable using external PC, sometimes shakers are includes (it's can be helpful but it's not a prerequisite)
