i made my own and couldn't be happier. all you need is an old refrigerator or freezer, some heat tape and a proportional thermostat. you'll also need a fan . some people use a computer fan, i was able to use the original circulation fan that came with the upright freezer i built mine from. it's well insulated so temps are very stable, it's got a ton of space inside so you can incubate a lot of eggs and it's a heck of a lot cheaper.
you can find people giving away old refrigerators and freezers everywhere.just check the freebies section of your local classifieds.
i spent less than $200 on mine. the helix t-stat was $129, 4 ft of 11" heat tape w/connectors was about $20 and 4ft of 18" shelving from lowes was $10 -$20, can't remember exactly( it's been awhile).
i set my helix at 89 degrees and it's been holding like a champ.
