I'm not sure which way to go as in electric or gas, I've got a double garage to brew in as I don't want to take over the kitchen for 3 hrs as SWMBO would keep tutting

Can anyone give me the + & - on both?
Is the temp more controllable on an electric heater than gas?Or does it not matter that much?
Was thinking of getting this 50 litre one http://www.homebrewbuilder.co.uk/hlts%2 ... ttles.html I understand that this can have a heating element added if I wanted to go electric?
I'm sure there'll be more questions as I get near to my first brew
