At one stage I had 6!
My first an LPL 66II, followed up by the addition of a Meopta Opemus II which was given to me by a friend. I then picked up another Opemus II and a gazillion others bits and pieces for $100.
Next up, I got into colour printing for a while, and splashed out $695 for an LPL 6700 which became my workhorse as I was able to modify to also allow me to print from my beloved Kodak Junior 6x9.
Landed my next LPL 7700 for $10 - including 2 lenses, 4 carriers, Novex timer, an 11x14 easel and a quick-mask 8x10 Saunders easel.
My latest acquisition is an LPL7452 head for $25/case of beer, which will actually end up costing about $600 once I get the column and counterweight delivered from Japan.
Parted out most of these now - covered the outlay of the original LPL66 and 6700 easily enough, so once I've got the 4x5 up and running, I'll be seriously contemplating selling the 6700.
For now, operational-wise I guess I've got 1.5 enlargers on the go.
