You can flash with serial no problem, but if/when your modem gets bricked(and it WILL!) you need a jtag to fix it. At least get a Blindcat usb - for 35.00 it will make your life sooooo much easier if you plan on testing for awhile. It's point/click and it takes about 20 seconds to flash a 51xx compared to 20 minutes on a pjtag. If you know that you are hooked and you know that you are gonna test until they pry your cm out of your hands then cough up 60 for a usbjtag nt and never look back.
