Oxygen & Acetylene setup advice

One thing I find disturbing is the high price of local used torch parts. I occasionally search C/L and attempt to search Phlakebook Marketpharce, and some of what I find is so high priced you might as well go buy new. This is especially true when you add in the possibility of damage by poorly trained users, and just plain wear and tear. Some time back, Ox-Arc had the little Harris suitcase setups on sale complete with full tanks, and I am kicking my *** for not buying one. I tried to get them to trade me for a Victor torch by paying some boot but that did not go over well.
