Well for 18 months or so I did all my E6 (Sensia) processing. With currently available kits, it is a fairly mechanistic process, you just have to follow the instructions precisely as to time and temperature.
On the plus side it cut my processing costs in half, meant I could get important shots processed quickly, and allowed me to push or pull film as required. On the down side, it takes quite a bit of time.
I think the difficulty of temperature control is a bit overplayed by Jwenting - though I appreciate he is simply relaying what he was told - any instructions I have read require temperature control to within .25 degree, but only for the first developer (its a 3 stage process) which takes 6 -7 minutes. While temperature control is also important for the next 2 processes, variations of .5 degree are OK.
Furthermore, if you get the time temperature slightly wrong all that will happen is possibly a slight colour cast and less than perfect density (but slight exposure errors could cause this as well) - if you intend to scan the slides, these are all easily corrected.
As to facilities - all my processing was done in the kitchen sink. All you really need are a very accurat thermometer and a water bath at the right temperature to sit the tank in.
Is it worth it? Only if you really need to cut processing costs and/or need a quick turn around after a shoot. The processes eats up about 30min. of your time per film - what is that 30 min. worth to you? There is no element of fun or creativity involved.
It suited me because a) I had the equipment anyway for B&W work and b) E6 processing locally was both expensive and took 3-5 days.
As for examples, any of my Sensia shots in the last 18 months were home processed.
