If you have the older style cross feed (no bearing) it would be best to also upgrade the new cross feed leadscrew assembly. My customers that have also upgraded to the new crossfeed leadscrew are amazed with how much better it works.
The power feed kit is not too hard to install, just take your time. If you Google 'Taig Owners Club' I posted a how-to guide with photos. I can't include a direct link from CNC zone to another forum, sorry.)
