We love our butcher block island! My hub did a poly coat and we don't have to deal with the oiling and other maintenance. We don't cut on it.

I love mine. Stained with coffee and sealed with tung oil. I've not cut on mine, but had used food safe finishes so I could do food prep with no concern.

A thought on resale - I believe it has a good solid universal appeal.

I hate my butcher block counters. Oiling leaves marks on your papers you set down (or food boxes) for weeks after you oil them. I finally gave up with the oiling so I wouldn't have to deal with that. There is a finish called Osmo Top Oil that is supposed to be good and I plan on trying it. You can put it over previous finishes and it doesn't leave oil marks.
They don't handle heat well. I burned mine with a pot by accident.
As far as cleaning goes, I use those Lysol Kitchen wipes. It is easy to clean and care for. Water really doesn't bother it.
I am not going to change them because I think they will help sell the house and I don't plan on living here long enough to justify replacing them. My kitchen came from IKEA. The previous home owners installed it. IKEA's farmhouse sink is to die for if you want a new sink.

It definitely takes a certain type of homeowner to want butcher block as the surrounding surfaces. Wet areas should be finished with a waterproof finish like SatinSeal (no oiling needed). More typically folks butcher block for the island- not the surrounding work surfaces. Islands are the new kitchen table and wood is much warmer and not as "clinky" when setting down a wine glass or coffee mug as stones and faux materials...
