Our negotiations in December fell through b/c we were about $10K off in valuation. You keep using that 2008 purchase of $17.5K as the valuation, when in fact there's a much more recent sale to use as a basis: https://namebio.com/exerciseballs.com
I can offer you a price where you walk away with a profit and don't have to deal with retired pastors or divorces or other excuses that keep you saddled with a domain you no longer have time to develop. But if you're stuck on that $17.5K valuation, then I'll leave you to find a buyer at that price who finally follows through.
