Hello and welcome to APUG Joe.

Yes, there are processors that can make life easier when processing E6 films, but it's not strictly a necessity. It can be done with standard tanks, but the tricky part is temperature control. Depending on the chemical kit you'll use, it can be simplified to less than the 6 standard steps. Another APUG member (Tim Walls) has written a guide here. If you're going to use the Kodak kit, this publication has some information. Go to page 3 to see the steps involved and have a look at the temperatures. From some point on, there's no need to be very accurate and the process has quite a lot of tolerance regarding temperatures. People who have done it say that it's doable, although rather tedious. In any case, you'll nedd an accurate thermometer.
