Tapmaster is an easy retrofit and usually goes in after the cabinet is in anyway. You just drill a hole in the toekick that gets covered by the pedal. You might need to fish the line through to a hole in the back of the cabinet for the neatest install but it's not bad to do in a new cabinet. (It would be gross to do that in my current nasty old cabinet which is why I haven't done it. Ewwwww.)

Thank you, fori!

Combined with comments to my other thread, I think Tapmaster it is.

Mine was installed right after my cabs went in even though I had the TM on-hand prior so I don't see any difference with you installing one now. I did, however, have my cab maker/installer drill the holes for it so my plumber's job was easier. I figured my cab maker was better at drilling nice holes than a plumber. Very easy, and I really, really love my Tapmaster Euro 1775.

If you buy from Conservastore try using save10 as a coupon code. And call a couple of days after you order it to tell them you need it ASAP, it took them about a month to get me mine,
