recon steering box supplier

Im in need of an exchange 3 bolt steering box due to my 'new' secondhand box leaking worse than the original after only a few months due to a slightly wobbly input shaft (i have a seal kit but assume replacement of the bearing would require a full strip down ?)

They can be had from paddocks and from ebay and one such supplier who happens to be the cheapest at £150 claims to re re chrome the shafts ,does anyone have any experience with these boxes and are there any suppliers i should stay away from ?

Thanks
