spindle bearings, buy new or service the old???

[Doubletrouble 10]

I need to replace all three spindle bearings on my 36" deck. I thought I saw a post on here somewhere about just replacing the bearings and reusing the shaft and housing. Which way would be better/cheaper. I found new ones on e-bay for around $75 for all three. What would just the bearings cost and how difficult is it to press the old out and install new? Thanks

Well I would say if you can buy 3 for 75 dollars then buy them....that is a good price for one.....
