I'm sure others will be happy - however I know the Manx Museum is currently in process with a team of volunteers 'flattening' wills ready for digitisation - I'm not sure what years they are doing (I suspect working back in time tho) thus some images might be made available - otherwise choose your film, rent from your nearest LDS Fam Hist Centre and get busy - many FHC's allow images of microfilm pages to be put on USB thumb drives otherwise a modern ( greater than 8 MPixel) digital camera from micro film reader allows you to work at them at leisure tho I find it easier to use 2 computers one showing image the other the transcribed will.
pre 1700 wills are often short but often difficult to read on film, post 1800 get longer + longer (with often poor handwriting) as the 19th century progresses - I've summarised some 60%+ of 18th C wills on MNB
