J&L brought in a few 1/4hp Pacific Crest units with internal dual control for well under $1000 ( I think they were $800 and something .) This was a while back though.
Have you checked the U-grow shops? In Calgary they sell a DIY type setup. Just need a controller. Maybe less then above idea. Noise??
Also have you considered all the drawbacks of operating a chiller?
