Well, since I last posted over 4,000 days ago (2009?) I saw a bidet seat at Costco and got one.
Relatively easy DIY install, and works relatively well. I would prefer a stronger spray but patience is rewarded.
A plus, besides being more clean, is that TP usage has plummeted. It's only used to sop up any remaining water and check to make sure, er, that the bidet did its job.
They aren't cheap - between $200 and $300, but IMHO well worth it.
I have read that some drill out the jets for more flow. I'm thinking about it.
