Just a heads up that I was going to go the Slikstick route as well. I tried to call and email them a couple of pre-sales questions, but never heard back from them. I ended up going with an X-Arcade unit, the tankstick. It's less than half the price of the slikstick units and showed up on my doorstep in a week.
They've been excellent support-wise, even answering the phone the day after Thanksgiving. Even though the unit may not have as many options or buttons as Slik's it's got everything I need, plus it comes with a tough surface coat on it already, so you don't need to spend extra on an overlay.
Oh, and mamemarquees carries side art, marquees and bezels to match the X-arcade logs.
