You don’t need to overspend on a specially built editing workstation. I edit and encode digital video and make DVCAM masters on a weekly basis, not to mention doing DVD authoring and other graphic design work, and I am still using a two year old Dell P4 desktop computer (and Dell laptop as well) with an inexpensive firewire card, some external hard drives and the simple video card that came with the computer. Save yourself some money and get a fast P4 or new dual core pc from a major manufacturer and you are in business. Use the savings to buy a deck or some software if you need it.
