While I don't want to get too specific or get too edit-y, since player valuation requests are not permitted, I bought a 32 year old player this offseason with roughly mid-80s TSP and 7 potential, with a transfer comparison range of 400k-450k. If I can find a guy 11 years younger with similar skills, for under 100k, I'm an idiot. Well, I may be anyway.
And of course, my 20 year old trainee with 7 pot has a compare range of 550k-600k currently, though I didn't get him for $1000 - it cost me $2000, which cuts dearly into my profits.
