EF aircon compressor noise

Hey guys, just wondering if anyone knows if JUST the bearing for the aircon compressor can be replaced for cheap?? or is it better to replace the whole compressor?

My aircon has been broken for ages and recently since i tried to have the car regassed it has been making a noise and slowly to now has been getting worse and worse :(

I dont really cair if i cant fix the aircon, its the bearing giving way that i'm worried about because its connected to the main belt (****in multi belt!!)

If its gonna cost too much i may aswell get a new compressor and get the aircon working again i suppose

has anyone had this happen before??
