I recently bought an Xecuter3, and the reason i chose it over the Xenium, was the Control Panel, so i thought i would buy the chip and the pro switch now, and then later when i got another paycheck, buy the control panel and the LCD screen. Now, on the online stores, they say there is an option to buy it without the LCD screen, but it doesn't say if you can without the Pro Switch. Can i? Could i right from Xecuter? I don't want to waste $20.
