I have a chance to buy a used 3 HP oneida cyclone for $800 and was wondering if you all think that is a wise buy. The unit was bought in 2001 and has the original filter and motor. It looks to be in good working order and I will have a chance to see it run before I purchase it (I will however travel to travel 250 miles). The price includes a small about of ductwork, maybe $150 worth. The 3HP for me is overkill (I have been in the market for a cyclone for awhile now and the people at Oneida have been consistent with me in saying that I only need a 2 HP unit). The new 2 HP cyclones are $1380 plus another $250 for shipping, so the $800 for the used 3 HP looks pretty attractive.
I do not know how many improvements oneida has made over the last 7 years. Is the 2001 3 HP cyclone really any better than a 2008 cyclone? Plus how much longer is the motor likely to last? Anyway, I would really like your input as I need to make a decision by quickly--I would like to pick it up this weekend, if possible.
