Chiller recomendations

Hello all I am looking to add a chiller to our 120 and was shocked at the price that a LFS quoted to us. I have found a few on e bay that meet our requirements. First they must be large enough for our tank, second and most important they must be affordable, especially this day and age. So here they are for your consideration:

ECO PLUS 1/4 HP WATER CHILLER 170 GAL AQUARIUM FREESHIP - eBay (item 110372549080 end time Jul-02-09 09:09:17 PDT)

1/3 HP Via Aqua Aquarium Chiller / Water Cooler NEW! - eBay (item 230347973672 end time Jun-18-09 10:46:11 PDT)

Aquarium Chiller 1/4 HP Water Cooler UP to 175 Gallons! - eBay (item 280356007770 end time Jun-15-09 13:25:41 PDT)

I am leaning toward th Via Aqua for two reasons, first the price and second it is actually larger than I would need so it will not have to work as hard to cool the tank.

Thanks in advance

 

I asked about this same chiller awhile back, and here is what was said.
