I want to pick up an airless for occasional use, and unfortunately the budget is tight.

I have a chance to buy an old Binks Super Bee for about $200, (dirty but working) and I thought some of you are probably familiar with those. However, I'd rather spend more for an entry level new machine if that makes more sense. Has the technolgy improved much over the years?
A Graco 190 is what I've looked at for a fairly inexpensive new machine. I know the Binks was more expensive in it's day; would it be a better machine now?
If going new, is there something other that the 190, in that price range, that you think would be better?
BTW.. I'll mostly be spraying latex, primer etc.
Thanks....
