yes i got the T862A, the one with an 800W pre-heater and a 200W overhead lamp, i can actually see what's going on, keep an eye on the solder as it melts and poke things with a stick if necessary.
I don't dispute the benefits of a T862A, but get oven, destroy a few boards until you got it timed to working 100%, and then its a doddle to plant components, press go, and get working board with near 100% reliability.
