You may be able to buy them cheap these days, my comment is more to do with repairs and upkeep. Unless you do all the work yourself and do not factor in the cost of your time, they are not cheap. In a few years people will buy 'cheap' L405s and get bitten by the same issue. As soon as electronics came in, cheap went out and the L322 is heavily laden with electronics.
See you in the forum, when the 'help!!' posts start
Addit: oops looks like you're already there.
