It's true that any marine recycle or consignment store is likely to have a good stock of these old stoves, because, indeed, most of us are onto propane. Unfortunately many of them are not in great shape, but they are very inexpensive so you could probably buy a couple and cobble together one good one!
After living (relatively happily) with an alcohol stove for over 10 yrs we have switched to propane, and honestly wouldn't go back.
The lack of preheating & pumping is too convenient, and the price of quality alcohol for the stove was outstripping the cost of beer!!(well.....almost)
