Anyone got some links for do-it-yourself racks? 6-10 tubs, something fairly small.

I've already seen Tim Bailey's. Which I like, Tim's a great guy...and has a great guide and build material list, but I'm looking for something smaller.

This will be my FIRST rack system and I am leaning towards pre-built, heating installed, and possibly thermostat installed as well. Ready to go.

But I have an urge to check out some do-it-yourself builds first.

Thanks
