There are ways around the price aspect. A drysuit (new) can be had for around 400.00. Dacor suit closeouts were offered at the price. Check archives under hot deals etc. Some of the stock Bare units are in the 500-700 range news. Underwear? I use old polypro. , or fleece as underwear. Sometimes I use a wool sweater. I also use the expensive stuff, but sometimes I find my homemade underwater just as capable and versatile. Additionally, the shelf life of a drysuit will often exceed the lifespan of a neoprene wetsuit. I have had suits last as long as 16 years.
Historically, in the olden days there was no drysuit training to speak of. I learned from and with folks who were trying them for the first time. There were a lot of upside-down adventures. I guess what I am saying is that it isn't all that hard, nor need to be costly.
Regulators? Computers. Personally, I don't much care for computers as they always go funny. Believe me...they do. I have six, or seven sitting in my office. The most dependable setup is to use a depth/timer like the Uwatec and write down tables on Wetnotes. Very cheap, very dependable. Regulators can be pricey. However, sales abound. Apeks are nice units. Reasonable too.
BP and wings. Used a Hammerhead plate and check Ebay for sales on wings. As these things evolve people often unload their perfectly fine models for the newest hot rod.
Again, I stress comfort, longevity and safety - that comes in the form of a drysuit.
