Chiller for a 29 Gallon BioCube?

Hello all. First post here.
I am new to the world of aquariums but I dove into the hobby head first and I've been learning fast.
I started out with a 14G BioCube for my office which has been running almost 3 weeks now and is going quite well with two Ocellaris, a paired off Pistol Shrimp and Randall's Goby, Royal Gramma, Blue Damselfish, 4 hermits, and 4 snails.
Last night I also picked up a 29G for my house, along with everything needed to start it. At this point it has 20lbs of live sand, 18lbs of live rock (more in a week), and has water at 1.023.
Last night when I was filling the 29, I was adding water that was about 90F. I got the tank running and let it go for a while but the temperature wasn't really dropping. Finally, using ice and cold water, I got the temperature to 78F. Then it started increasing again with no influence from me. The lights were on at the time and the room temperature was around 72. I turned off the lights and went out for a couple hours. When I came back the tank was still holding at 79 (the lights were off and the room temp was down to 62).
Today the temp was down to 76 but the events of last night were cause for concern. As we move into summer I don't want to risk losing hundreds in livestock to a temperature spike. I want to be proactive and get a chiller/heater that I can just set to a temperature and have it keep the tank there.
What's the cheapest, smallest unit I can get for a 29 Gallon?
Coincidentally, when I came into the office today, my 14G had shot to 80.5F (it usually sits at 78). All day I've been battling with it so I also need a chiller for that. Cheap is the key here. I've spent enough on the tanks that I can't afford the perfect chiller. What can do the job?
Any help will be appreciated, but please don't suggest things above $300, as I just can't do it.

most chillers are in the 200-300 range. Never seen one for cheaper than that, typically have an electronic thermostat.

That is too many fish for a 14 gallon.
Since biocubes are closed hoods, the temps shoot up in them and can get around 80 easily. During the summer, I had a fan blowing on the top of my biocube to help cool the hood and I left the little top door open. It kept it at about 79. I had ice bottles in the freezer and ready to go if anything got too hot.
