Great post Longtime!
I would just like to add, (IMHO) that for those who are taking it one step at a time (like me) just to get over the first hurdle of PPLH it's worth budgeting for more hours than the minimum 45.
I'm aiming to get mine in around 65 hours, (part time, whilst working full time, over a 12 month period) and then reviewing my finances!!!!
I am led to believe averages vary between 55-65 hours.
If you decide you can't go further than this at least you can have the pleasure of enjoying one of the best hobbies in the universe!
I'm presuming your cost's have been estimated on flying the R22.
Granted if you do it all in one go you will probably take less time...
