G'day Seebreasy,
I run an 70l Indel Isotherm fridge and have been impressed with it to date. Top loader, external compressor, quiet. Keeps things cold for ages, you can make it either a freezer or fridge by simply adjusting the temp. Unsure of what you consider expensive, it cost about $1500.
Power consumption is pretty good (300w/24H). A 400ah house bank , not doing anything else, will keep ice for 7 days without charging ( knock off a day or even two if you keep opening it all the time).
Cheers,
SB
