Heh. I don't have any pics right now but its just a simple stainless braid in the bottom of the MT. The only problem I have had with the RIMS tube (it's the one from Stout Tanks) is that the way its configured new with a probe on one end, the probe was not giving accurate temps. I reconfigured it so that the probe is inside of a 1/2 tube and it is much better. I give the mash a stir now and then but the temp stays very steady.
The kettle has 2 4500w elements. I start heating as soon as the elements are covered and I've never timed it but I would say at worst it gets to a boil about 10 mins after I'm finished sparging. Sometimes it gets to a boil before I'm done sparging.
My biggest bottleneck right now is heating strike water which takes about an hour. However, I have a dryer plug that's close
