I have an older delta (around 1992, I know that's not that old).. It is
a dream to work with.
Of course now, I'm not sure if they've "value engineered" it in the
past 12 years, but at the time it was hands down the best quality.
IIRC, it was about $200-250 more than the Jet, but worth it.
The general problems you will have with the cheaper bandsaws is that
the wheels won't be balanced as well,etc.
Whatever saw you buy, get Mark Duniskinge's book on tuning the bandsaw
(probabaly mispelled his name)
