I have the ICR 1500, the same unit as the PCR-1500 but has the remote head and it works very well. There is no noise from the PC leaking through to the unit, I'm sure you will be very happy with it, further more the software uses very little of the PC resources and therefore no impact on the ARB. Unless you really need the dual receive facilities of the 2500 save the money and buy an antenna instead.
