First off just pull the trigger you won't be disappointed. Secondly I just got myself a Mighty and had very similar questions myself, which the lovely people on this forum have been providing some great answers to over the past few days.
From what I've gathered however is that pretty much every accessory for this bad boy is solid and there's a decent variety of pretty cool things you can get to enhance and alter your vaping experience with the crafty/mighty. I would try out everything that it comes with initially to see what you really like and then go from there. Two things the unit doesn't come with which I highly recommend are a water tool adapter (
@Ratchett has the most reliable and highest quality adapters as far as I can tell) and a glass mouth piece (if you like seeing vapor production while you're hitting it rather than waiting to exhale to see just how beautiful the vapor quality and production is with this beast).
I've been recommended extra CUs and plan to buy at least one more in the near future. Also people seem to be very impressed with the dosing capsules. The unit comes with one so you don't need to buy some right away, but if micro dosing, prepacking bowls, or keeping your unit cleaner at all spark your interest, then I would probably buy the 8 pack with the magazine holder.
Oh and the last thing I've been recommended is a stand, expecially if you buy the mighty because it doesn't stand by itself very well.
