i always like to go for the cheap alternative of things

my newest idea is rack from ikea:
http://www.ikea.com/au/en/catalog/products/70120023 http://www.ikea.com/au/en/catalog/products/50101233
thats a frame that can fit 6 42 x 55 x 15cm for $20 and the racks are only $9 each
that $72 + a heat cord and thermostat and you have yourself a cheap rack system for hatchlings
what do you guys reckon?
edit: this is my 100th post yay!
