Welcome here!
Cheap Chillers. Yes, possible, indeed..... but not advisable.
The mear fact that you are at a stage where you are looking into Chiller possibilities, puts you on a performance level comparable to that of doing Land-speed-record preparations for next season. that is where "CHEAP" equates to knocking off 1 layer of carbon fibre from the rear suction duct. just to save a couple of thousand dollars on a 200K project. this is where cheap becomes dangeorous.
now that I've said that, ignore it...

you can get real bigass performance for not all that much.
