Some of the vendors didn't get back to me in the last few days, so I've decided to go with Cointaker. I've spoke to Melissa on the phone a few times over the last couple days and she has been very helpful. They are also local, so I'll save on shipping by going there to pick it up. They had the best price and for the most part, everything I've read about them have been positive.
I'm getting a Metallica Pro that includes a shaker motor. I'll be picking it up in about 2 weeks once we close on the new house and finish the move. Apparently Star Trek is going back on Stern's line in September, so they will be available for awhile. Metallica is coming off the production line and Melissa didn't know if it was going to go back up again or now. That was most of the reason I went with Metallica.
Thanks to everyone for all their help and support!
