Hovabator and reptibator vs. the pricier incubators?

[redshepherd]

I'm looking at them here on big apple herp: http://www.bigappleherp.com/REPTILE-SUPPLIES/Incubators

I only need to incubate one or two clutches at a time, so looking at really small time incubators. Do any of these incubators on that site work well? Which one should I get? For those who have used one of these, have you needed to make some modifications/add something to improve it?

I'm not handy at all, and I'd rather spend some extra money to just buy a suitable incubator than to build one..

Or which incubator do you recommend for just one or two clutches?
