I traded a 2008 Tacoma on a 23 Frontier last year. No problems with the Frontier. I have only driven it 3000 miles, however. The one criticism of the Frontier is that the shifting of the the transmission is a bit rough. I found the same thing in the 23 Tacomas I test drove as well. The 4L with the 6 speed auto in the Tacomas was a great combination. It's a shame they went away from it.
