Quite a few of us have been through this. I think all the aftermarket options are very robust and probably much better than "oem". I know RLS makes a great setup too. I replaced my own with the sector 111 system. Just make sure it gets done right and they check the oil cooler thoroughly too. Can't say how long it should take a shop....probably took me 12 hours working methodically. It was the first clam-off job I have done on the Elise.
Where in TX? I am north side of Dallas. PM if you have any questions.
