I've only had one fail (get a temperature controller no matter what) and they do keep up really well.
If you decide in-line isn't the way to go, you may want to consider the extremely thin Cobalt products. They're great for hiding in a corner. About the same price point as Hydor's in-line product, though.
Get a Hydor inline heater and Temperature Controller STC-1000 with sensor. My water temperature is always at 23.5c +/- .3 degrees. If the temperature drops .3 the heater will go on if it goes up by .3 the fan kicks in. I Love it.

Reason: Wrong name
Unless it's a Sulawesi tank, I wouldn't put a heater on at all.
It gets down into the 50s in my house (I like it cold when I sleep and since I'm at work all day, I VERY rarely turn on the heater). Will shrimp be ok in tanks that cold? I thought they needed it in the 60s at least.
My two CRS tanks are opposite sides of my room, one is 66-68, the other is 72-74, so the warmer one is for the moms to go into to give birth and the colder one, everyone is fine in. I rather not heat it than worry about a heater screwing up and toasting my tank. The moms I moved got berried in about 64 water.
20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.
It gets down into the 40s at night (sometimes even the 30s) and during the day (when it's usually no lower than the 50s), the back door is wide open for the giant dog. So yeah, the house gets down into the low 50s quite often. Today it's 51 outside. So I expect the house is too.
